To extend Darhazer's answer

It's more like, except _.throttle is called imminently and then again after delay milliseconds

function throttle(func, delay) {
    var timer = 0;

    return function() {
        var context = this,
            args = [].slice.call(arguments);

        clearTimeout(timer);
        timer = setTimeout(function() {
            func.apply(context, args);
        }, delay);
    };
}
