if you dont want to use lasIndexOf or substr then why not just look at the string in its natural state (ie. an array)

String.prototype.endsWith = function(suffix) {
    if (this[this.length - 1] == suffix) return true;
    return false;
}

or as a standalone function

function strEndsWith(str,suffix) {
    if (str[str.length - 1] == suffix) return true;
    return false;
}
