This seems to be a pretty small subset of JavaScript, but I personally love small projects like this for educational purposes. Removing the noise and keeping things minimal helps my brain reason about things.

Earlier this year I enrolled in an online class called "Building a Programming Language" taught by Roberto Ierusalimschy (creator of Lua) and Gustavo Pezzi (creator of pikuma.com). We created a toy language interpreter/VM and the final code was around of 1,800 lines of Lua code. Keeping things as simple (and sometimes naive) as possible was definitely the right choice for me to really wrap my head around the basic theory and connect the dots.

Thanks for the link.
