React JS

What is React JS?
React JS is a JavaScript library used to build interactive user interfaces. It is based on the idea of components, which are reusable building blocks that allow developers to create faster and more efficient web applications. React JS also uses a component-based approach to building user interfaces, which means that developers can easily separate the presentation logic from the rest of the application, making the code easier to maintain and modify.
Why use React JS?
There are several reasons why developers choose to use React JS to build web applications. These include:
- Efficiency: React JS uses a virtual DOM reconciliation algorithm that allows developers to update only the parts of the user interface that need to be updated, making the application faster and more efficient.
- Reuse: React JS components are reusable building blocks that can be used in different parts of an application, which means developers can save time and effort by not having to write the same code over and over again.
- Maintenance: By separating the presentation logic from the rest of the application, the code becomes easier to maintain and modify. It also means that different teams can work on different parts of the application without interfering with each other.
