Answer 1

I converted the answer from the Python question into Javascript after doing some research on the Python language:

function OverlapTest(input, compare) {
    for (var i = 0; i < input.length; i++) {
        if (compare.startsWith(input.substring(i))) {
            return true;
        }
    }

    return false;
}

This will return true if the strings overlap at the start and end and false if they don't.
