var testString2 = "Loremipsumalotof changes to be tested";

var testSplitTitleCase = (str) => {
    return str.split(' ')
        .map(w => w[0].toUpperCase() + w.substring(1).toLowerCase())
        .join(' ');
}

var testRegExpTitleCase = (str) => {
     return str.replace(/\w\S*/g, function (txt) {
        return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
    });
}
