I want to add a space between a lowercase and uppercase in one string. For example:

FruityLoops
FirstRepeat

Now I want to add a space between the lowercase and uppercase letters. I don't know how I should start in JavaScript. Something with substr or search? Can somebody can help me?

var str = "FruityLoops";

str = str.replace(/([a-z])([A-Z])/g, '$1 $2');
