How to properly forward forward props in state?

Question

React

How to correctly forward props to state?
I use class field syntax and do it like this:

state = {
  text: this.props.text
};

Here I heard an opinion from one developer that this is wrong, like "this should be inside a non-static method" and needs to be initialized in the constructor. He is right? state in what way does it relate to this, is it not a method?

That's right. Only he does not understand that such a record is not static, and after the transpile it will end up in the constructor.

Answer 2

constructor(props){
super(props)
this.state={
  text: this.props.text
}
}

this is how it should be. But if your method works, then why not use it?))))

Answer 3

In general, classes are like that, there are React Hooks . There's no need to write this in principle.

Answer 4

In general, logically, you need to use props directly, the state stores only what can change during the operation of the component itself with the same props
