The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

	// I have written a lot of different `str-replace` Sass functions over
	// the months yet none of my tries were succeeding in making the new substring
	// able to contain the one to replace (e.g. `str-replace($str, "a", "ab")`).

	@for $i from $start through $end {
	$output: append($output, nth($list, $i), $sep);
