A tiny interpreter and compiler which shows the basics of compiler development.

For more details see the source or my blog post "Implementing a Simple Compiler on 25 Lines of JavaScript"

Along the implementation you can find sample (and simple) implementations of:

• Lexer which produces a list of tokens (module for lexical analysis).
• Parser which produces an Abstract Syntax Tree (AST) (module for syntax analysis).
• Interpreter which traverses and evaluates the AST.
• EBNF grammar.
• Recursive Descent Parsing.

Here it is!
