AoC 2016 done with easylang
easylang does not have many features and has a simple syntax. It is statically typed and has as data types only strings and numbers (floating point), arrays of strings and numbers, and arrays of arrays. Arrays can grow. Programs compiled into an AST tree run in the browser or in the browser IDE. There are built-in features for canvas graphics.
It can be useful as a teaching and learning language due to its reduced feature set, simple syntax, browser IDE, and built-in graphics.
However, since easylang has no built-in functions for special things like sorting or hashmaps, you have to program them yourself, which makes the programs longer, but in a way more informative.
