To convert string to camel case in javascript.

camelCase.js

function toCamelCase(str) {
    return str.toLowerCase().replace(/(?:(^.)|(\s+.))/g, function(match) {
        return match.charAt(match.length-1).toUpperCase();
    });
}

function toCamelCase(string) {
    string = string.toLowerCase().replace(/(?:(^.)|([-_\s]+.))/g, function(match) {
        return match.charAt(match.length-1).toUpperCase();
    });
    return string.charAt(0).toLowerCase() + string.substring(1);
}

Small changes to the above to allow for kebab and snake case input, as well as proper camelCase rather than PascalCase as @mcarlucci pointed out.

EDIT: I tried the gist from @assembledadam above but it did not seem to work for me.
