Lightweight JavaScript Libraries contained in 1kB

Each year, a unique JavaScript game development competition takes place within one month, starting on August 13th, named JS13KGames. What's interesting about this competition is that there is a filesize limit requirement on the submitted game source - the entire game must be packed in 13kB ZIP archive. In 2016, I participated with Skip'n Glitch, a two player competitive logical game involving strategy and arithmetics. The game has a single player mode set against a simple and predictable but challenging AI opponent. Two players can play against each other on the same device.

I had no problem compressing the game in 13 kilobytes. However this would not be easy if some useful lightweight libraries were not prepared in advance. They include a basic tweener for styles and transforms in 900 bytes, a sound controller with 9 predefined sound effects in 750 bytes and a pixel font with a full set of glyphs (10x5px size) in 1250 bytes. Here are the scripts in action:

As the web tech is evolving, the flash player for web browsers is getting more and more obsolete. For example the biggest advertising platform - Google's DoubleClick dropped support for flash ads. I'm not speaking against the flash technology, which is still viable for game development (it can be easily compiled for mobile or wrapped into Steam). However in web there are new heroes and one of them is the HTML Canvas. I've already shared some lightweight JavaScript libraries used in #js13kgames and today I'm sharing another class - Lens Flare effect!..
