Expression Compiler

1. write a custom grammar
2. in your grammar, return one of the token types for javascript (i.e. define how the AST should look)
3. the compiler will automatically convert that to a function for you, to call against a scope

Install

node:

$ npm install expressionjs-compiler

browser:

$ component install expressionjs/compiler
