Javascript RegExp: How to remove all charcters after // until a new line

Question

Basically what I want to do is parse code, and remove all comments made with "//", including the "//", until a new line appears. I don't know how to effectivly do it in Regex unfortunately.

Some example code might look like this:

variable += 10; //comment to be removed.
more code...

so only "//comment to be removed." gets removed

This will allow you to parse the code, instead of just removing the comments from a string:

var code = getCode();
var stripped = '';
var regex = /(.*)\/\/.*/g;
var result;
while ( result = regex.exec( code ) ) {
    console.log( result );
    // Do other stuff with line of code
    stripped += ( result[1] + '\n' );
}
