React Context is a library that helps to reduce the amount of code that is needed to be written in order for a React application to work. It does this by providing a set of helper functions and methods for handling context.

The React Context is a JavaScript library that provides a way to pass data from one component to another. It is often used for passing data between parent and child components. But there are other alternatives available, such as:

  • setState() method: In this case, the parent component will call the setState() method in the child component, which will trigger an update of its state. The parent component will then re-render itself with the updated state.
  • props() method: This approach is similar to using setState(), but it differs in that it does not trigger re-rendering of the parent component. Instead, it passes down props() values from the parent to child components.

Context API is a useful feature, but because every context update re-renders all of the context's consumers, it can cause performance issues if not handled wisely.
