Ever wondered about learning Web Development and different aspects of it, but then got confused as to which framework to use? There is no need to search further if you are new to Web Development and want to learn about the finest framework. In this blog, you will get introduced to ReactJs which is aimed to help you understand the know-how of ReactJs.

Keep reading, as you are about to unveil the knowledge of the best framework used in Web Development!

Stepping into the blog!

Jordan Walke, a software developer at Meta, invented React after releasing “FaxJS,” an early version of React. XHP, a PHP HTML component package, impacted him. In 2011 it was first implemented in the Facebook News Feed, and then in 2012, it was used on Instagram. In May 2013 at JSConf US, it was made available as an open source.

What is ReactJs?

A front-end, a back-end, and a database are the three main components of a web application. The technologies employed in all three are replaceable, depending on the degree of compatibility clauses, as long as the use case stays the same. Having said that, React is one of the most popular and frequently used front-end libraries today. ReactJS, among other technologies, distinguishes itself by allowing us to simply reuse UI components.

An open-source JavaScript library called React sometimes referred to as ReactJS, is used to build single-page web apps. It’s a popular library for creating UI (front-end) for online and mobile apps. React helps developers to create mobile and online apps that are speedy, adaptable, and intuitive. It also allows them to streamline the design process. ReactJs developers may use its capabilities to create whatever they desire without being bound by tight constraints.

Plugins and libraries for ReactJs may be simply integrated with existing code. It also lets them create web apps that are quick, scalable, and easy to use. With the introduction of React in front-end development, much-needed server-side logic was restored.

You can opt to learn ReactJs from different platforms, all you need to look for is ReactJs online course. However, it is advised to always check the curriculum and understand the different aspects that will be included in the course and then pick the most beneficial one.

If you have understood what ReactJs is, then let’s move to the next important question: why do we need to use it?

Why use ReactJs?

React offers significant untapped potential for creating lightweight, resource-efficient, and resilient application solutions. Here are a few listed below:

  1. ReactJs has testing capabilities making it easy on the developer’s side to analyze the performance on different devices.
  2. ReactJs is SEO-friendly, helping the website to run faster and boost performance speed.
  3. ReactJs is declarative as it uses DOM (Document Object Model) making it easier and understand the code.
  4. ReactJs is mobile-friendly which makes it the most advantageous over other frameworks.
  5. ReactJs is stable and has a solid foundation that employs downward data flow.

Interesting isn’t it how there are so many advantages and reasons to use ReactJs? But one important situation is left to be addressed here: the prerequisites needed to learn ReactJs.

It is highly suggested that you have a basic understanding of HTML, CSS, and JavaScript. ReactJS uses JSX, which has a syntax that is almost identical to HTML. As a result, a prior understanding of the HTML language is quite beneficial. JavaScript, on the other hand, maybe studied concurrently using our ReactJS project.

Now that we have read about the requirements to learn ReactJs, let’s dive into the features of ReactJs since it has been a really popular framework!

What are the features of ReactJs?

React, as it is concerned with the front end, solely makes up for the ‘View’ element of the MVC (Model-View-Controller) application cycle. React can use Node to be rendered on the server side relatively quickly, with the potential to run native applications with React Native. Here are some of React’s distinguishing characteristics:

  1. React Components: We can construct UI elements in the format of ‘components’ using React. The purpose of using components in the life cycle of development is to enable code reusability, make the code lighter, and give the correct project structure. Later in this ReactJS lesson with examples, the chaining of many React components together to create code reusability is explored.
  2. JavaScript Syntax Extension (JSX): JSX is used to merge HTML code web design components with JavaScript functionality, utilising a syntax that is nearly equivalent to HTML. This is used to reduce backend server load and focus on client-side resource consumption for frontend web application parts.
  3. Flux: It ensures that the application data flow is unidirectional (one-way).

Let us now see what’s in the future for ReactJs as you are learning it today.

What lies ahead for ReactJs?

Many factors point to ReactJS as the future of web development, and here are some listed for you to know:

  1. In 2021, ReactJS is the most prominent front-end framework/library.
  2. As of 2021, ReactJS has surpassed jQuery to become the most popular web framework among software engineers globally.
  3. There are now approximately 1,114,016 React websites online.
  4. ReactJS is maintained by Facebook and developer communities throughout the world, and there are numerous forums where thousands of React users aid each other with best practices, contributing to the library’s future.
  5. Because of its scalability, extensive documentation, simple learning curve, and capability to produce the most adaptive solutions in the shortest amount of time, ReactJS has a competitive advantage over Angular or VueJS.

We have almost reached the end of the blog, so let’s wrap it up by discussing everything so far.

What have we learnt?

When you have to construct a single-page app with dynamic content, ReactJS is a fantastic technology to employ. Additionally, the ease with which React handles issues like two-way data binding, declarative programming, and customised DOM rendering contributes to the framework’s appeal. React provides a user-friendly API with strong functionality and a developer-friendly method for creating UI components that render HTML elements with the accompanying CSS styling.
