- Parser: Generates an Abstract Syntax Tree from the tokens created in the lexer. The parser takes the token objects and builds a tree that represents the relationships of the different parts of the code, that is then turned into JavaScript using Escodegen.

- The parser is brokend up into over 20 files, that handle different parts of the parsing process

- ```parser.js``` is where the different modules come together to build the final tree output

- ```rearrange``` are a group of functions that take the original tokens from the lexer and rearrange them in a manner that is conducive to building the AST so that it produces the equivalent JavaScript output of the Swift input
