What do you actually want to do here? It returns 'mr.null' only if you enter null in the prompt & that's your default condition when no input is matched. If you add another else if to check for literal null string it can alert a different text message. If that's what you want to do. https://code.sololearn.com/WxkJ38t2H9no/?ref=app

The behaviour is same on firefox. It's not a bug that's the expected output. when you cancel the prompt, return value is null. When it's pressed ok without a value it's empty string. # Read below for info about prompt. https://developer.mozilla.org/en-US/docs/Web/API/Window/prompt

@Lord Krishna it works fine with the empty one and pressing Ok,cuz it gives the answer I want,problem is,chrome seems like not knowing what null is, or not wanting to receive it,what I'm looking for is an alternative for null in Chrome

@Lord Krishna I'm not looking for The Null,I'm Saying what should I put instead of null Because this version of chrome I'm using doesn't accept null as the code,playground is fine with it,IE too,but only chrome has problem with it
