Was working on fixing some test cases in js, tried everything i could but part of test case was never executing.
After couple of days of pulling my hairs, found someone had overriden the test lib methods by mistake😭😭

Wait, how??

@psukys in js, u can override anything including predefined libraries

Try this in browser console :
Math.floor = function() {
console.log("hello world");
}

And now Math.floor() will always say "hello world" 😪

@abbasc I probably didn't emphasize where "how?" Points to 😅 I meant how come does production code override test code in your environment? :(
