How to copy all props into state?

Question

JavaScript

When I started learning react, I saw somewhere that all properties are copied to the state, in the constructor. Maybe I'm already confusing something, but is there such an entry: this.state = {props}?

Answer 1

There is one, but most likely you have seen this : this.state = {...props}
Then you won’t need to write this.state.props.foo, you can contact through this.props.foo.
In my opinion this is bad practice and should only be done in some very limited scenarios.
