Reference for built-in JavaScript types in node or v8

Question

I'm writing some code that will do some introspection on a Function in node. Specifically, I want to hopefully do non-standard-JS things like listing source code line numbers. However, there appears to be no reference documentation available on global types in node/v8 to see what's available.

The Global Objects documentation for node doesn't have this information. Although MDN documents Function, it only lists standard methods/properties or its own non-standard extensions. Also, its compatibility chart focuses on browser JS engines. It helped me find the name property of a function at least.

The REPL isn't helping me either:

> function foo() { }
undefined
> foo
[Function: foo]
> console.dir(foo)
[Function: foo]
undefined
> Object.keys(foo)
[]
> Object.keys(Function.prototype)
[]
>

Is there any sort of reference documentation for global node types?

What do you mean, "global node types"? Do you expect there to be any non-standard methods? — Bergi

Are you planning to write some native code or how do you think introspection will be possible? — Bergi

I hoped there was a non-standard method available, but as getOwnPropertyNames shows, I'm SOL. Oh well. — Jacob

function allProps(obj, name = '') {
     if (obj == null) return; // recursion to the final link in this prototype chain
     console.log(name, Object.getOwnPropertyNames(obj));
     allProps(Object.getPrototypeOf(obj), 'prototype');
}

allProps(Function, 'Function');
allProps(Function.prototype, 'Function.prototype');
allProps(Function.__proto__, 'Function.__proto__');
