What is React JS?

A JavaScript library for designing and developing the UI of websites and web apps is known as react js. It allows you to create interactive elements on websites.JavaScript is a scripting language that enables users to build and manage dynamic content on their websites (such as slideshows, animated graphics, interactive forms, etc.). For instance, When you hover your cursor on the ‘Courses’ button on upGrad’s homepage, a drop-down menu appears. That’s an interactive component, and you can build one through JavaScript.

You should note that React is not a framework unlike Angular; it is an open-source project and helps you create user interfaces. It is the ‘view’ layer of a Model View Controller application. An essential highlight of React is that it allows you to make components. Those components are reusable HTML elements. This means you can reuse them to create a user interface much quickly and efficiently. Apart from components, React has state and props that allow it to streamline data storage and handling.

If you’re unfamiliar with JavaScript, understanding React can be a bit challenging, and hence let us understand what a JavaScript library is and how they function to understand.


What is Javascript Library?

One of three core web development languages (the other two are HTML and CSS) is Java Script. It handles the interactivity of a website and how it behaves. JavaScript is crucial for websites as, without it, they lack any dynamic features to help them stand out.

You’d encounter some instances where you have to perform repetitive tasks such as creating a stock animation effect while using Javascript. That’s why developers use JavaScript libraries Since writing the code for such repetitive tasks every time can be tedious and annoying. React is also a JS library, and it focuses on simplifying UI development. A JS library is a collection of JavaScript code you can use to write standard JavaScript functions. This way, you don’t have to rewrite the same code lines for a task every time. It saves you a lot of time and space on your editor while ensuring that your chances of making errors are minimal.

Why Learn React JS?

Attracts Great Pay

By learning React, you can bag various roles in the tech sector. For example, you can become a front-end developer that manages the client-side of a website. Companies pay handsome salaries to React developers because it’s a specialized skill, and there’s a massive shortage of these professionals in the industry.

Easy to Learn

React is relatively easy to learn in comparison to other libraries, programming languages, and frameworks. You must indeed be familiar with JS before you begin learning this library; however, you only need to know the basics of JavaScript for that. You can start building beautiful UIs after only several days of training.

Huge Demand

As the number of tech startups and apps is continually increasing, the need for React developers is rising accordingly and thus the demand for React JS developers in India is relatively high. UI has become a vital aspect of web development, especially since Google considers it while determining its SERP ranking. By learning this library, you’d add a highly demanded skill in your skillset since digital marketing companies, app development agencies, startups, and even significant corporations; they are looking for front-end developers that know how to implement React.

Saves Time and Money

React helps developers with coding the UI of their applications. Without React, it can get quite tedious for developers to write the same code lines all over again. Development teams use React as it helps them in saving a lot of time and resources. As we mentioned earlier, a JS library simplifies the coding of repetitive tasks to streamline your efficiency. As React makes the team more efficient, it allows them to use fewer resources and saves a lot of money.

To summarise, whether you’re a student or a professional, learning React will surely help you become a better developer. It’s an in-demand skill that enhances UI development substantially. You’ll be able to design better user interfaces for your web apps and projects after learning this skill.
