How to understand how the getInitialState method works?

Question

React

Hello. While studying React, I come across a description of the getInitialState method inside the component class. But the method (getInitialState) is not called anywhere. Is it some kind of internal component method? Help me to understand.

Answer 1

In ES6, the class constructor is used to set the initial state, and since there are no classes in ES5, this method and several others are used .
