JavaScript keys() function why is there no documentation

Question

I've spent about 20 minutes trying to find more information on the keys function in javascript...

I initially found the keys() function referenced in this answer:

hash = {"a" : "b", "c": "d"};
keys(hash); // ["a", "c"]

Does anyone have any more information on this function, especially browser support?

You are probably looking for this: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… — Jonathan

That's not what I'm looking for Jonathan, Im looking for the documentation for the keys() function not the Object.keys() method or the Array.keys() method. — chim

Well, look no further. There is no such function in JavaScript. — Jonathan

There's no such function, it's part of the console api

Description for chrome console: https://developer.chrome.com/devtools/docs/commandline-api#keysobject

For Firefox: https://developer.mozilla.org/en-US/docs/Tools/Web_Console/Helpers

Yep, I've since tried this in a script and it throws Uncaught ReferenceError: keys is not defined

@Andrey, please don't answer documentation requests like these. Questions like this should be closed as off-topic.

This is not a documentation request. This isn't a JavaScript function and that's why there isn't any documentation. So it's a valid question and the answer is valid, although perhaps the answer could be more explicit, (that would be a bit pedantic though). However, I will delete this question if you think that it should be deleted. @Cerbrus
