Chef.js is an effort to implement a JavaScript interpreter for the Chef programming language. Parsing the recipe was done by writing a context-free grammar representing the language, then using Jison to create a parser from that grammar.
Chef's specifications were originally described by David Morgan-Mar. The helloWorld.chf was also taken from his website.
Although the goal is to stay as close as possible to the original, the behaviour is not guaranteed to always match this document. As a result, the Fibonacci Numbers with Caramel Sauce recipe offered with the specifications does not work with this interpreter.
