Any tools for generating JavaScript code from AST

My friend and I want to learn how to create your own programming language, which is performed by compiling JavaScript code. And now there are many languages ​​that compile in JavaScript. So far, I have learned simple simple methods to analyze code from source code and run it in JavaScript.
But for now, I cannot create good code. Since many projects have done this, I wonder if there is any standard tool out there, and with that I can generate JavaScript from the AST, which got the original form syntax?
