Amongst all the frontend technologies, React JS is one of the most popular choices amongst the developers to create innovative websites and applications. With its modular architecture and advanced features, React JS can be used to create web applications with less coding. It offers a good amount of tutorials and documentation to help developers learn and implement it.
When developers are building a component, they should define its render method. This can affect how it performs and the amount of time it takes to render. In React, components are built like functions in JavaScript.
When a component is re-rendering, it should also set its state. This is done by using the setState() method. This is one of the features of React and it will enqueue updates to the component’s state.
React’s virtual DOM is a copy of the actual DOM, but it updates only the parts of the page that need it. This is faster than the traditional full refresh model, and increases the performance of the application.
A component can also receive props. These can be strings, functions, or arrays. These props keep the component and its children in sync (more information).
A React component has its own internal logic, which makes it easier to manipulate. This logic helps developers reuse components and improve the productivity of application development.
In addition, React JS is compatible with iOS and Android devices, making it easier to deploy your application to a wide range of devices. This is a great advantage for developers who are developing mobile applications. It also helps in lowering the development costs.
