Javascript variable names are not minified

[DonaldDuck313]

If I start with this code for example:

function foo(bar){
    return bar + 1;
}

This code gets minified to:

function foo(bar){return bar+1}

I would expect it to get minified to something like:

function foo(a){return a+1}

Minification is not obfuscation. Changing variable names is a more complicated process and can easily break the code.
