Recursion

[at0g]

Hello, would you be willing to support recursion on objects/arrays?

I've implemented it in my project using the following (ES6) - I would have sent you a PR, but coffee script is not my thing.

// Apply a morph function recursively
function morphObjectProps (obj, fn) {
    if (!obj) {
        return obj;
    }

    if (Array.isArray(obj)) {
        return obj.map((item) => {
            return morphObjectProps(item, fn);
        });
    }

    return Object.keys(obj).reduce((memo, key) => {
        let value = obj[key];

        if (typeof val === 'object') {
            memo[fn(key)] = morphObjectProps(value);
        }
        else {
            memo[fn(key)] = value;
        }
        return memo;
    }, {});
}
