I'm going through a JavaScript problem with this and I don't understand something.

function Cat(name) {
    this.name = name;
    inner();
    function inner() {
        //A
        console.log("A", this.name); // this is too long so had to use this.name
    }
    //B
    console.log("B", this);

    //C
    ( () => console.log("C", this) )();
}

var myCat = new Cat('Markov');

I don't understand how it prints the right value for ()=>{} arrow functions that's inside IFFE. Can someone enlighten me?

I thought the scope of this inside an IFFE with arrow would be window object :S

You don't have a traditional IIFE here. Your arrow function itself is immediately invoked. It certainly isn't *inside* an IIFE. – Quentin Jun 29 '18 at 18:30
What do you mean .. it's still uses ( ..function) (); – TechnoCorner Jun 29 '18 at 18:33
`()` just forces it to expression context, it doesn't represent a function. – Quentin Jun 29 '18 at 18:34
