What is hooks in React JS?
Hooks are functions that let you “hook into” React state and lifecycle features from function components. Hooks don’t work inside classes — they let you use React without classes. You can also create your own Hooks to reuse stateful behavior between different components.
What is mount and unmount React?
The main job of React is to figure out how to modify the DOM to match what the components want to be rendered on the screen. React does so by “mounting” (adding nodes to the DOM), “unmounting” (removing them from the DOM), and “updating” (making changes to nodes already in the DOM).

How long it takes to learn React?
In short, becoming proficient with the basics of React will take you between one and six months. The exact time to master React depends on your prior software development experience and the time you are willing to dedicate toward learning.

What do I need to know about react?

For an introduction to React, check out Thinking in React instead. The key feature of React is composition of components. Components written by different people should work well together.
What is a component in react?
In React, components describe any composable behavior, and this includes rendering, lifecycle, and state. Some external libraries like Relay augment components with other responsibilities such as describing data dependencies. It is possible that those ideas might make it back into React too in some form.
