What are the advantages of React?

Below are the list of main advantages of React,

1. Increases the application's performance with Virtual DOM.
2. JSX makes code easy to read and write.
3. It renders both on client and server side (SSR).
4. Easy to integrate with frameworks (Angular, Backbone) since it is only a view library.
5. Easy to write unit and integration tests with tools such as Jest.

Practical Code Example

// Core Advantages: High performance via Virtual DOM, rich component ecosystem, unidirectional data flow
function ReusableButton({ variant, children, onClick }) {
  return (
    <button className={`btn btn-${variant}`} onClick={onClick}>
      {children}
    </button>
  );
}
