How can I read ‘native code’ JavaScript functions?

rated 0 times [ 96] [ 4] / answers: 1 / hits: 65836 / 13 Years ago, wed, february 1, 2012, 12:00:00

Is there any way to see the declaration of JavaScript native code? Whenever I try to look at a native function in Chrome or Firefox, it says native code:

> String.fromCharCode

function fromCharCode() { [native code] }

What does this mean, and is there any tool which can help me to read actual code?

The reason Chrome or Firefox says that the code is native is that it really is native - the WebKit and Firefox developers have coded up that functionality in C or C++, not JavaScript. However, if you want to see the actual code, you can look at the source repositories for Chromium and Firefox.
