What is React?
Initially, React was introduced by Jordan Walke, a Software Engineer at Facebook. Later Facebook developed it further and deployed it on Facebook’s newsfeed and Instagram in 2011 and 2012, respectively. React was adopted because of most of the Developer Communities. Because of its reusable UI components, and it is ultra-fast at large web pages. ReactJS is an open-source library, and one of the trending libraries has more than 152,000 stars. You can visit the React repo to contribute anytime.
Main Feature of React.
- Reuseable Components – React allows the reusing of components that saves time. Designers create Components like form, brand logo again and again. React deletes that repeating job completely. But it can be painful to bring change in a particular. But Updates can be the easiest part. You can update all the reused components at once without disturbing others.
- React Virtual DOMs – A regular DOM(Data Object Model) tree gets updated every time there is a change in elements. A DOM tree has thousands of Elements in this era. The process of updating the DOM affects Web Application. But React manages a virtual DOM of itself that increases the updating process. It updates even minute changes by the user without affecting the other parts of the interface.
- Data Binding- React uses downward data binding that prevents changes in the parent element if the child element got changed. Because of this, the code becomes more stable. But on the other hand, the JS-representation view model has a disadvantage of changing the parent element if the child got changed.
- React Hooks- React has two types of components that are: Functional and Class-Based. Only class components support local state or have to use state management frameworks like Redux for global state. In February 2019, React developers introduced a new feature called React Hooks.
