From a Udemy React student

The instructor helped me whenever I needed it, and I've learned a lot in very little time. Now I can create simple single-page applications, and I fell in love with CodePen and VS Code!

Learn more about React

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

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.

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.

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.

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.

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. Reacts 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.

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.

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.

All Node.Js courses

Learning Node.js is a great way to get into backend web development, or expand your fullstack development practice. With Udemys hands-on Node.js courses, you can learn the concepts and applications of this wildly useful JavaScript runtime.

From a Udemy Node.Js student

If you are wanting to learn how to; build for production, push to production, have a dev and production version, and learn how to navigate the two, this is the class for you! Seriously there is so much real-world knowledge here it should be worth way more than what it is!

Learn more about Node.Js

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.

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 Chromes 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 its easy for teams to learn, and its fast. Examples of applications that use node.Js include video conferencing apps, chat servers, eCommerce software, and collaborative online gaming.

What are the advantages of Node.Js?

Node.Js is open-source, meaning its 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. Its 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 its the preferred choice for real-time communication applications and programs that need to be highly scalable.

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

A runtime system is a platform where a software program runs. Its 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, its 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. Its an efficient system, making it the preferred choice for many software and tech companies.

From a Udemy Express Framework student

After taking this course, I decided to adopt Node.js as my specialized language/technology. Thank you.
