When to choose ReactJs over other in making responsive UI

React is a front-end library, focused on building user interfaces for web applications. Facebook created React.js in 2011. In 2012, Instagram also started using it. It can, be combined with other third-party libraries.

It used Markup and JavaScript in a single file. They started the component-centric approach for separating concerns. Many large companies started using React.js.

React native

Applying React.js concepts so that you can make it towards React Native to develop mobile applications. You can now create mobile apps using React Native. React Native’s mobile apps compile the JavaScript you write to native code, and feel like other platform-native apps.

When to use

Not every project needs or should use React. React is a high-powered tool, in conjunction library like Redux or MobX. If involves different, dynamic inputs, buttons active/disabled, user login – then the project may be a good fit for React. React helps you manage those changing states and views to the user based on state information.

Reusable components

A React component can be anything in your web application like a Button, Text, Label, or Grid. Components are first class members in React and supports the creation at any time, combine, with other components.

It also speeds up the process of making changes to a component.
Something that has been built once can get reused in multiple places.

Redux

Redux provides a single state container. It follows a simplified flux pattern where you keep all your application data. It becomes a single source of truth and it makes it easier to manipulate relevant data. This happens in the memory, so it is speedy.

Using JSX

JSX is a simple well-known HTML tag with no fancy attributes. It makes use of React’s API calls and finally renders HTML. JSX allows you to mix your HTML directly into the JavaScript, Doing so allows your code based on logical concerns. React can easily transform that JSX code into a compatible format. JSX syntax allows for expanded functionality.

Efficiency

Efficiency comes from React’s use of a Virtual DOM by keeping a virtual copy of the page’s DOM. We will see more about the virtual DOM in the following topic. When a change occurs, React compares the current DOM with the incoming change. Instead of the entire thing, this causes the browser to only re-render a small part of the page.

This makes React much more efficient where changes occur frequently. React is remarkably flexible. you can use it to build quality user interfaces. Its library approach has allowed to evolve into a remarkable tool. You can change a small part of your existing application by using React, and you can start converting your whole application into React.js.

Virtual DOM

React minimizes DOM changes. efficient and intelligent. JavaScript is fast, but updating the DOM makes it slow. With the Virtual DOM, React monitors the values of each component’s state. React compares the existing DOM state with new when a component’s state changes and then it update the DOM. React handles it very well behind the scenes.

Benefits like avoiding layout trashing, when the DOM element changes. So, saving battery and CPU power is very important.

Storybook

Storybook supports the component driven design concept. It also provides designers and developers to build highly reusable components which they will live in the application.

Support community

Reactiflux is a community specially in helping solve and share React-related problems. There are over 250k questions asked about React and related libraries.

Conclusion

React is an excellent tool for mobile, web, and other platforms. React’s popularity and usage are increasing day by day and coding in React makes you better at JavaScript.
