JavaScript library that executes scripting language in browser

Question

Is there some JS library that could execute script written in some other scripting language (like Lua) in a browser environment. E.g. something like this.

TheLibabry.executeScript(scriptCode, apiObjects, timeout);

I know about eval() function, but I need a script to run in isolated environment i.e. do not have access to my code. And I want some simple, classic imperative language like Lua or even basic. Also, I want to be able to set a timeout for this script. I.e. limit execution time.

Writing a compiler from scratch in JS could be a good idea. Given that you don't have to worry about memory stuff and the parsing can be delegated to Peg.js or similar, that isn't as scary as it sounds. — georg

I am not sure I am ready to write one more compiler right now. — Denis

You could try leveraging WebAssembly to run different code languages.
