Answer 1

In ES6 you can use normal function or Arrow Function:

Function1 (Normal Function)

functionA(){
   //Something here
}

Then should call this.functionA()

Function2 (ArrowFunction)

functionA = () => {
   //SomeThing Here
}

Then should call this.functionA

*Function3 (Eg: in a const of React) *

const A = (functionTest) =>{
  return (
     
{functionTest}
    );
}

functionTest is mapStateToProps in React :)

I hope it is helpful for you :)
