Why do object and class have different this?

Question

JavaScript

Why does this refer to the class in the first case, and to Windows in the second?
And how is this looked up when calling functions?

class Test {
    static t = this
}
Test.t

const obj = { t: this }
obj.t

Answer 1

Try creating a function on the object that will return this:

const obj = {
    GetThis(){
        return this;
    }
}

console.log(obj.GetThis());
