If you code in JavaScript, you should know all about debouncing functions.
When an event listener such as a window ‘resize’ fires, sometimes it will fire 72,000 times per second. That means your callback function is also firing 72,000 times in a row, bogging down the browser.
This isn’t as much of a problem as it used to be, but debouncing is still needed and should still be used.
So what’s the best way to debounce/throttle in JavaScript?
If you’ve ever created a website, you’ve surely used jQuery.
It’s a lovely JavaScript library that lets you do all sorts of whiz-bang Web 2.0 stuff while shielding you from the underlying plain vanilla JS functions.
But hang on a minute – do you really need jQuery?
The answer is, as usual, complicated… but fascinating!
JavaScript is THE super-helpful programming language that makes the whole internet go.
From Google Docs to online mapping, JavaScript makes it all possible.
Despite its popularity, many concepts in JavaScript programming are rarely explained in a simple, down-to-earth way.
For example: the self-executing function.
What in the Sam Hill is that all about?!

Introducing PikaJS: a jQuery-like JavaScript library that simplifies the client-side scripting of HTML.
I had been using jQuery and PrototypeJS, and I needed to ditch PrototypeJS at long last.
My colleague Michael Franzl said, “Hey! Check out this Balalaika thing!”
So I did.
Unfortunately, Balalaika doesn’t give you many methods to do cool stuff. That’s left as an exercise for the programmer…
So, I decided to make my own jQuery, and PikaJS is the result!
