Regex to replace multiple spaces with a single space

Question

Given a string like:

\"The dog      has a long   tail, and it     is RED!\"

What kind of jQuery or JavaScript magic can be used to keep spaces to only o

Answer 1

I have this method, I call it the Derp method for lack of a better name.

while (str.indexOf("  ") !== -1) {
    str = str.replace(/  /g, " ");
}

Running it in JSPerf gives some surprising results.
