ReactJS bind method to class component

Question

Im doing ReactJS course in Codeacademny and they confused me.

(EDIT - full code) Photo of the code :

and there's no constructor or anywhere call to any bind method for the scream class method.

However in further exercises they tell you can't do that.

I probably miss something.

Answer 1

Apparently this.scream is an arrow function. Arrow function does not require binding. It points to the right context by default.

scream = () => { ... }
