Answer 1

function titleCase(str) {
    var result = '';
    for (var i = 0; i < str.length; i++) {
        if (i === 0 || str[i - 1] === ' ') {
            result += str[i].toUpperCase();
        } else {
            result += str[i].toLowerCase();
        }
    }
    return result;
}

titleCase('peter piper'); //"Peter Piper"
titleCase('teXt mEssAge'); //"Text Message"
titleCase('more to me than meets the eye'); //"More To Me Than Meets The Eye"
