ReactJS – All You Need to Know About It

Home » Web Development » ReactJS – All You Need to Know About It

React is basically a JavaScript Library used by developers to build a user interface. It’s is painless to work with React resources that are available in tools, IDE’s, libraries etc. React is among the widely used framework in the sector. The report by the HackerRank 2018 Developer Skills showed that React created a big gap between the percentage of developers who are aware of the framework and the size of the current employer. This shows that it is now the right time to implement React.

React was first deployed in Facebook’s newsfeed in 2011 and later it was deployed on Instagram in 2012. React does not provide a complete application framework. It is basically designed specifically for building user interfaces, so it does not include some of the many tools that developers might consider necessary to develop an application.

  • React Set up

When you want to get started with React, consider using the most straightforward set up possible e.g., an HTML file which imports the React and Reactdom libraries using script tags. There are two ways to complete the setup: you can write the code in the browser, or you can set up a local development environment on your computer. Writing code in the browser is the best method because it is the quickest way to get started.

  • The Components

React is all about components, which usually contain JavaScript classes. You can make a component by using the React-component class. You can then define the method of the component, for example, the method can be render method. Inside the render, you can specify what you want React to display on the pages.

  • Handling Data

There are two main types of data in React: the Props and the State. The differences between the two are a bit challenging but when working with them, it becomes easier to understand. The main difference is that for the state data, it is private and can be altered from within the component itself. The Props are controlled externally and not by the component.

  1. The Props

The big part of React is the reusability, which means that you are able to create a component, and then use it again it in different ways, e.g., to display a different message. To achieve reusability, you have to add the props.

  1. The State

The other option of keeping data in React is in the component’s state. Unlike the props which can’t be altered directly by the component, the state can. So, if you to change the data in your app, for example, basing the changes on how users interact with your app, you must keep the data in a component’s state somewhere in your app.
