Created by the professionals of the Meta community, React is an open-source Javascript library that allows designing complicated user interfaces (UIs) through pieces of code known as components. React has adopted a declarative approach. The render method returns you a description in the form of a render element resulting from what you have coded through components. To put it in other words, React’s render method demonstrates whatever you ask it to show based on the description you give as a component. For example, if you are inserting a Shopping List component, React would render the equivalent file of the shopping list available on your database.

Why Use React?
Although there are many React coding challenges, the primary purpose of React is to simplify the creation and the usage of user interfaces and large web applications. It eliminates the need to reload the page when dealing with large applications as it operates fast and straightforwardly. At the end of the day, React was designed as an advanced solution to DOM (Document Object Model). The latter was functioning slowly, and the Facebook leaders needed a faster solution to operating more efficiently. Now, with the help of React’s virtual DOM, you will have no worries about UI updates and page reloads.
Furthermore, React is reusable and is known for its SEO friendliness. Its reusability is a big advantage since it eliminates a huge amount of work by saving time and effort. For example, suppose you are designing a new web application and want to use a component you created for your earlier applications. In that case, you can easily reuse it and save your time in creating the same components again.
The chances are high that you might have heard of JavaScript but might not have come across React. The main reason for this is that JavaScript is an older and more traditionally used language, while React is a newer and more advanced version of JavaScript that presents the features and the functionalities of JavaScript in a simpler and less time-consuming way. To back up this point, companies like Facebook, Instagram, Reddit, and Netflix comprise the population of React Users.
For motives like these and more, React has almost 5.7 million users in comparison to its main competitors, Angular and Vue, which have 1.7 million and 167,000 users, respectively.
