# What javascript-only KoTH challenges have there been?

## Alternative title: Look! I made a thing!

The recent Formic Functions challenge was a lot of fun, and seems to have taken the concept of easy-to-run online javascript-based king-of-the-hill challenges to a new level. It's inspired me to make a framework for building them, which I invite people to take a look at!

(I have a vague idea for a KoTH challenge of my own, which I plan to build with this framework)

For those saying "wait, haven't we seen this before?": I for one think that the ease of just visiting a website and typing in some code gives this new style a much lower bar-to-entry for competitors, and the ability to develop games without any setup whatsoever (you can literally download the code and open the html files) gives a much lower bar-to-entry for contest writers.

## My Question

I've been cloning past challenges to drive out the functionality, but so far I've only found 3:

There must be others out there. Does anybody remember any?

• Personally, I don't think this is really on-topic for meta, but I won't VTC just yet. If you ask in chat, however, I'm sure people will be willing to help out. Sep 9 '17 at 15:56
• Wow, Your Formic Functions one runs so fast. Sep 9 '17 at 15:58
• @cairdcoinheringaahing I had the same concern, but there are some not-too-old questions here in the same vein, so I thought I'd risk it. Also I wanted this to be a bit of a collection of javascript-based challenges, which I think meta can do better than chat.

• Wow web workers really make a difference - runs fast even on mobile. I have lots to learn... Sep 10 '17 at 9:05
• I wish the formic one was a screensaver :) Sep 13 '17 at 16:38
• @FrenzyLi sounds fair. davidje13.github.io/koth-webplayer/formic.htm#screensaver (use with your choice of website-as-screensaver program). Wouldn't recommend leaving it on for too long though; probably not good for your electricity bill!

• codegolf.stackexchange.com/questions/67560/… is a javascript based KoTH Jan 9 '18 at 22:52

• @Dave The difference is that that request searches only questions. You can get similar functionality from the search box by using is:q.
• You can also search specifically for tags by enclosing the tag name in square brackets. For example [king-of-the-hill] [javascript] Feb 4 '18 at 17:41
