How can I see how native js functions are implemented in a browser?
I've tried Math.floor.toString() but it returns "function floor() { [native code] }" and I can't step into the function using debugger.

1I don't think the native source code itself is present in the compiled executable. Do you? – John Weisz May 04 '16 at 08:36

because the function internally benefits from native code implemented on the browser level – or hor May 04 '16 at 08:36

1Native = compiled code of the browser not a javascrit function so you can't. – Walfrat May 04 '16 at 08:38

You cannot access the code unless it is available through github for example for the given browser. – The amateur programmer May 04 '16 at 08:46

You can't do this from the console, because the functions are part of the compiled browser executable … or, rather, its JavaScript engine. It is native code.
You may be able to read the source code for that engine, though, depending on which browser you're using. For example, Chrome's v8 source is on GitHub.

It's a native function. I'm guessing you could download the source code for a browser, as that's where it's implemented
