Anybody help with RegEx?

Hi all

Can anybody tell me why this isn't working. I've been staring at it for hours.

function LetterCapitalize(str) {
    return str.replace(/\b[a-z]/gi, function(x) {
        return x.toUpperCase();
    })
}
letterCapitalize('hello world');

It's supposed to target the first letter of each word then capitalize them. Regex editors online say it's correct. Help

Paul

Your regex is great! When I tried to run your code, though, I noticed your function is uppercased in the declaration, but lowercased when you call it, so that might be the problem you're having! You'll also need to either modify the function or store the result in a variable when you call it, right now it's returning the capitalized string, but you need to capture it somewhere in order to use it. I just popped the call inside a console.log() and got Hello World :-)
