hooks in react typescript | hooks in functional components react explained in detail

Description:
Welcome to this video from tutorialsinhand.com. In this video we are going to discuss on hooks in function components in react.

What are hooks in Function Components in React?
We know that in JavaScript / Typescript, we can call one function from that of another function and use the output from the other function in the current function. Similarly in React also we can also use one component from another component.

Hooks are basically functions. Before the introduction of hooks in React 16.8, class components were used to make stateful components and function components were used to make stateless components. Stateful component means the components could maintain a local state apart from the global application state. On the other hand, stateless components are basically pure functions which for same input, produces the same output.

But after the introduction of hooks, developers could use state and separate the logic for maintenance of state and side effects from the main component in functional components, hence making them stateless which further increases code reusability. Besides this, they help the developers to "hook into" React state and lifecycle features from functional components.
