What is web development?

Web development is a broad description of the tasks and technologies that go into creating a website. It can be as simple as making a static text-based website or as elaborate as developing an interactive dynamic website. You can break web development into two different categories: frontend (client-side) and backend (server-side). Frontend code executes on the user's computer. This can include HTML, JavaScript, and CSS. Backend code runs on the server — this commonly includes communicating with a database and often involves languages like Python, Ruby, Java, or PHP. Web development does not necessarily include the design process — it focuses on code. A web designer builds wireframes to mockup their vision for a website and then shares that with a developer. The developer is responsible for writing the code that implements the design.

What are the steps to becoming a web developer?

Some web developers will obtain a degree or certification in the field. However, most jobs don't require a specific degree or level of education, just demonstrated knowledge of the field. So, it is more important that you know how to show off your skills. You could highlight your skills through relevant work experience or a portfolio of past projects. You might also share code you have developed using a platform like GitHub, or participate in solution-based forums like StackOverflow that reward you for helping others. HTML, CSS, and JavaScript are the first three coding languages you'll need to learn to break into web development. You need these three essential elements to create a modern website and work as a frontend web developer. HTML (Hyper-Text Markup Language) specifies the content of the website and builds the backbone. CSS (Cascading Style Sheets) styles the content. JavaScript controls the interactive elements of the website.

How long does it take to become a web developer?

The answer to this question will depend on you. The more time you spend developing your skills, the faster you can become a web developer. The good news is that web development generally uses light-weight code that is easier to learn than many other languages. If dedicated, you can learn the basics of web development in a couple of months. But good web developers never stop learning. A better question might be, "What can I do to become a better web developer faster?" The answer to this question is practice. Becoming familiar with coding helps tremendously, but there is also a less obvious benefit of practicing. The more you code, the more you will run into problems or find bugs in your code. A significant aspect of web development is solving problems and debugging code. The better you get at solving problems and tracking down bugs, the faster you will get at coding.

full stack react js, express, nodejs, MongoDB: 

In this lesson, we will explain why we need a library or framework when developing applications with JavaScript.

Whether you're interested in adding React to your existing dev skillset, or you want to develop full-stack web apps by using tools like NodeJS, Redux, and MongoDB in conjunction with React, Udemy has a comprehensive selection of courses to choose from.

mern stack with react js: In this lesson we will define React. We will explain React features one by one.

React is an essential Javascript framework for web development. It is the most popular framework for developing web, mobile, and desktop app user interfaces.

react: In this lesson, we will explain the advantages of developing applications with React.

What is React?

React is a front-end library in Javascript that was developed by Facebook. The simplest definition of React is that it is a user interface library used for building UI components for the web. But if that was all React did, it would be little more than a template library. Developers define components in React by using an HTML-like syntax called JSX. These encapsulated components manage their own state, making it simple to pass rich data to a component and keep the state of the application and its components out of the Document Object Model (DOM). These features give React components the ability to react dynamically and efficiently to changes in their state. A set of simple components in React can be composed into either simple single-page applications or large, complex web applications.

REACT JS

What is the difference between React Native and ReactJS, and which one should I learn?

React, or React.JS, is a front-end Javascript library for building UI components for the web. If you are interested in web development, React is the perfect library to learn to create interactive, dynamic single-page apps, or even full-scale web applications. React Native is a framework for building native mobile applications for both the Android phone and Apple's iPhone. React Native is still React, which means the syntax and workflow for building applications are basically the same, but the generated components are different. In React, web components are generated. In React Native, the generated components interact with a phone's native APIs. If your focus is web development, then you should learn React. If you want to build mobile applications, it is best to learn React first and become familiar with the technology before you try React Native.

Web development with react, redux, nodejs, express, mongodb: In this lesson we will look at the difference between React and pure JavaScript.

Why is React so popular?

There are many reasons why React is popular. One reason is that Facebook developed it. The social proof is that if it is good enough for Facebook, one of the most popular social networks on the web, it should be good enough for other applications. React also solved many of the past issues that developers had with developing single-page applications (SPAs). React came out when SPAs were becoming popular, and all the existing frameworks to build them made development complicated and prone to bugs. One feature that makes it better than past libraries is that React is relatively easy to use. Its components are reusable, plus React's use of the virtual DOM makes it very performant. React should remain popular in the future as each new release brings new features and performance improvements.

Is React hard to learn?

Every technology or programming language has a learning curve, and React is no different. But it is easy to learn if you are dedicated and determined to create frontend web applications. To make learning React simpler, you should stick to the basics of React before you add any extra libraries, as that will only complicate your learning experience in the beginning. Since React is a Javascript framework, a solid grounding in Javascript will give you a head start. With this knowledge, the unique concept of JSX, React's templating language, and the way React uses state will be much easier to grasp.

In this lesson we will try to use React in an application without an easy installation tool.

In this lesson we will learn create-react-app, an easy setup command that I use when developing an application with React.

React with express, node, mongo DB: In this lesson, we will learn how to develop a single page application with React. For this, we will explain the logic in index.js.

Is React worth learning?

Yes, React is worth learning. There are a couple of reasons. The first one is that React is in high demand in the software development job market and has been for a few years. If you learn to code in React and can do it well, you will increase your chances of finding a job. This alone is another reason it is worth learning. Website users no longer will settle for old-fashioned sites that won't update without a page reload. React’s method of dynamically updating the HTML of a web page fits these users' needs and improves their experience. React has also been around a few years and has stood the test of time. A large portion of websites, both small and large, use React as a frontend framework.

React with redux, express, nodejs, mongodb: In this lesson, we will explain the errors you may encounter as you develop an application with React for the first time. We will teach you how to interpret these errors.

Is React a framework or library?

Frameworks provide an opinionated approach to building an entire application. Libraries, on the other hand, assist in building a single aspect of an application. With this in mind, React is a library. It assists engineers in presenting HTML in the browser. React has no opinions on how data is fetched, how styling is applied, or how the app is deployed or built.

React with redux, hooks and context: In this lesson we will create a component. Then we will learn how to use this component in our application.

How does React work?

React encourages engineers to write code using a Functional Programming approach. Engineers create components, which are normal Javascript functions. These functions return information to tell React what content should be displayed on the screen. The real power of React comes from the ability to nest or compose these functions inside of one another. This nesting ability encourages code reuse and allows an engineer to write a component a single time, but in many different places.

MERN stack: In this lesson we will examine the structure of JSX. We will talk about the properties of the JSX field.

What is React used for?

React is an open-source JavaScript frontend library. Some developers consider it a frontend framework because it does more than standard libraries usually do. The most common use of React is to build dynamic user interfaces for single-page web applications. But the structure of React makes it useful for more than just creating websites. JSX, which is one feature of React, is a syntax extension for Javascript that provides a template for the HTML and manages the state of the element. But JSX can be used as an interface for things other than HTML. React Native uses React to build mobile applications. Here, JSX becomes an interface for mobile UIs instead of HTML. There are even a few libraries that use React and JSX to interact with and manage hardware like React Hardware.

In this lesson, we will learn the different perspectives that React and pure JavaScript bring to the concept of separation of concerns.

React is an essential Javascript framework for web development. It is the most popular framework for developing web, mobile, and desktop app user interfaces.

react and node: In this tutorial we will learn how to do styling with React.

What does it mean that Node.Js is a runtime system?

A runtime system is a platform where a software program runs. It’s essentially an environment housing the collection of software and hardware that allows an application to execute (or run). Node.Js is a runtime system because it provides the environment necessary for applications to run within it, and no additional code or hardware is required. Because Node.Js makes use of JavaScript, it’s a runtime system that provides a framework where you can use JavaScript to create and run programs. The JavaScript programming language (which is quite popular) is then automatically translated into machine code for the hardware to run the program in real-time. It’s an efficient system, making it the preferred choice for many software and tech companies.

Reactjs, expressjs, nodejs and mongo db:

In this lesson we will learn the concept of props. We will learn how to manage data exchange between props and components.

What are the advantages of Node.Js?

Node.Js is open-source, meaning it’s a free code for all developers. On top of that, it also means that there is a thriving community of Node.Js users and programmers that all add to the knowledge base. Many are happy to share their flavor of the code with other developers, and collectively, the Node.Js environment continues to be enhanced. Because Node.Js uses JavaScript, there is a large pool of developers that understand and can code in the environment. It’s also a relatively simple environment for new team members to learn, making it an efficient choice for development teams with people that need training. Node.Js was developed on Push technology instead of web sockets, which is why it’s the preferred choice for real-time communication applications and programs that need to be highly scalable.

React JS with redux, nodejs, express js: In this lesson we will explain the concept of props and data flow through diagrams.

What is Node.Js and what is it used for?

Node.Js is a server environment built for fast and easily scalable network applications. It was built on Chrome’s JavaScript runtime and uses an event-driven, non-blocking model that makes it the best fit for applications that run on distributed devices and need to run in real-time. By using JavaScript, node.Js can be put to work by many software developers familiar with JavaScript. Because the code is open-source, you can also use it on any platform (Mac OS, Windows, or Linux). Node.js is the architecture for creating websites and real-time applications because it’s easy for teams to learn, and it’s fast. Examples of applications that use node.Js include video conferencing apps, chat servers, eCommerce software, and collaborative online gaming.

fullstack react with redux, hooks and context:

In this lesson, we will learn how to render lists with React.

Node.js is essential to developing real-time applications in JavaScript, and has been instrumental in the development of websites like eBay and PayPal. Node is designed around an event loop, which allows for easy management of asynchronous functions. This makes it a popular environment for modern developers working on chat and gaming apps.

In this lesson we will learn how to render lists conditional on a condition.

In this tutorial we will continue to see the conditional rendering that we learned in the previous tutorial.

In this lesson we will do conditional rendering in JSX domain with ternay method.

React’s method of dynamically updating the HTML of a web page fits these users' needs and improves their experience. React has also been around a few years and has stood the test of time. A large portion of websites, both small and large, use React as a frontend framework.

Is React hard to learn?

Every technology or programming language has a learning curve, and React is no different. But it is easy to learn if you are dedicated and determined to create frontend web applications. To make learning React simpler, you should stick to the basics of React before you add any extra libraries, as that will only complicate your learning experience in the beginning. Since React is a Javascript framework, a solid grounding in Javascript will give you a head start. With this knowledge, the unique concept of JSX, React's templating language, and the way React uses state will be much easier to grasp.

In this lesson, we will learn how to use axios, a 3rd party data extraction library. We will also use the async-await structure and try-catch block in this data extraction process.

In this lesson, we will explain what we will do in the section.

react js with redux, express, nodejs, MongoDB: In this lesson, we will learn to manipulate HTML tags by referencing them. We'll do this in pure JavaScript.

Why is React so popular?

There are many reasons why React is popular. One reason is that Facebook developed it. The social proof is that if it is good enough for Facebook, one of the most popular social networks on the web, it should be good enough for other applications. React also solved many of the past issues that developers had with developing single-page applications (SPAs). React came out when SPAs were becoming popular, and all the existing frameworks to build them made development complicated and prone to bugs. One feature that makes it better than past libraries is that React is relatively easy to use. Its components are reusable, plus React's use of the virtual DOM makes it very performant. React should remain popular in the future as each new release brings new features and performance improvements.

React js with redux: In this lesson, we will learn why we should use the useRef hook when referencing HTML tags. We will also explain other operations that can be done with the useRef hook.

What does it mean that Node.Js is a runtime system?

A runtime system is a platform where a software program runs. It’s essentially an environment housing the collection of software and hardware that allows an application to execute (or run). Node.Js is a runtime system because it provides the environment necessary for applications to run within it, and no additional code or hardware is required. Because Node.Js makes use of JavaScript, it’s a runtime system that provides a framework where you can use JavaScript to create and run programs. The JavaScript programming language (which is quite popular) is then automatically translated into machine code for the hardware to run the program in real-time. It’s an efficient system, making it the preferred choice for many software and tech companies.

What is React?

React is a front-end library in Javascript that was developed by Facebook. The simplest definition of React is that it is a user interface library used for building UI components for the web. But if that was all React did, it would be little more than a template library. Developers define components in React by using an HTML-like syntax called JSX. These encapsulated components manage their own state, making it simple to pass rich data to a component and keep the state of the application and its components out of the Document Object Model (DOM). These features give React components the ability to react dynamically and efficiently to changes in their state. A set of simple components in React can be composed into either simple single-page applications or large, complex web applications.

React Js with redux, express, mongodb: In this lesson, we will explain what a custom hook means. We will explain why we need to create a custom hook.

What is React used for?

React is an open-source JavaScript frontend library. Some developers consider it a frontend framework because it does more than standard libraries usually do. The most common use of React is to build dynamic user interfaces for single-page web applications. But the structure of React makes it useful for more than just creating websites. JSX, which is one feature of React, is a syntax extension for Javascript that provides a template for the HTML and manages the state of the element. But JSX can be used as an interface for things other than HTML. React Native uses React to build mobile applications. Here, JSX becomes an interface for mobile UIs instead of HTML. There are even a few libraries that use React and JSX to interact with and manage hardware like React Hardware.

React js with redux, express, mongodb, node js : In this lesson we will make a counter example. In this example, we will create functions in the custom hook that allow the values to decrease and increase as the button is clicked.

How does React work?

React encourages engineers to write code using a Functional Programming approach. Engineers create components, which are normal Javascript functions. These functions return information to tell React what content should be displayed on the screen. The real power of React comes from the ability to nest or compose these functions inside of one another. This nesting ability encourages code reuse and allows an engineer to write a component a single time, but in many different places.
