Any tools for generating JavaScript code from AST

Question

My friend and I want to learn to make our own programming language which runs by compiling to JavaScript code. And now there's plenty of languages which compiles to JavaScript. So far I've learnt basic simple methods of parsing code from source and running it in JavaScript.
But I'm not able to generate good code so far. Since many projects have done that, I'm wondering if there's any standard tool here, and with that I can generate JavaScript from the AST I got form parsing source?

escodegen would be nice. https://github.com/Constellation/escodegen
