this value in ExtendedScript

[Steven Charles-Charlery]

Hello, I have a problem with ExtendedScript, I have differents values of this in Chrome and ExtendedScript.

Why in third, fourth and fifth test, I have this = myObject.method ?

var myObject = {
method: function () {
alert(this);
}
};

myObject.method(); // myObject object in Google Chrome and ESTK
(myObject.method)(); // myObject object in Google Chrome and ESTK
(myObject.method = myObject.method)(); // myObject object in Google Chrome but method function in ESTK
(false || myObject.method)(); // myObject object in Google Chrome but method function in ESTK
(myObject.method, myObject.method)(); // myObject object in Google Chrome but method function in ESTK

Adobe  is using  ExtendScript which is something like ES3.
Back in ES3 things like object worked different. I'm assuming that there is some transpiling going on, which translates new ES6 features into ES3.
