How to 'merge' toml files about iarna-toml

@akkumar So the result of TOML.parse is just a JS object, so the usual approach would be to combine them with JS tools. Exactly what that looks like depends on your needs:

So you might go with the most simple option, with object composition:

const default = TOML.parse(default)
const prod = TOML.parse(prod)
const config = {...default, ...prod}

Or use a module for deep merging: (not an endorsement of this particular module, it's just what came up when searching)

const objectMerge = require('object-merge')
const default = TOML.parse(default)
const prod = TOML.parse(prod)
const config = objectMerge(default , prod)

Both of these methods can merge as many objects together as you like.

Something that might be cool would be a config library built on top of this library that provides composition of objects like this. Maybe something like rc but built on TOML instead of ini files.
