    function deepFreeze(obj) {
      const out = Object.freeze(obj);
      Object.keys(out).forEach(key => {
        if (typeof out[key] === 'object') {
          out[key] = Object.freeze(out[key]);
        }
      });
      return out;
    }

I think you meant "out[ key ] = deepFreeze( out[ key ] )" in the innermost step :-)
