Here is the code snippet:
'use strict';
var foo=function(){
alert(this);
}
var bar = {
baz:foo,
};
var x = bar.baz;
x();//1
After executing the code directly, everything works fine and it alerts undefined. However, when I insert a breakpoint at (1) and press F11 twice, it then alerts window.
Could someone please explain this behavior to me? Thank you.
After creating the jsfiddle and checking it out, I noticed something strange. When I added a breakpoint in 1 and tried using F11 with console.log or alert, all I got was undefined. However, when I paused at the breakpoint and manually called x() in the browser dev tools console, the results were different between Mac OS X/ Chrome (scope object) and Mac OS X/ Firefox (result is undefined).
This just goes to show that executing code in non-standard threads like the dev tools console can sometimes yield unexpected results that may not necessarily reflect normal JavaScript behavior.
