Convert arbitrary js objects into an array of array of array and so on while keeping the keys close to their values

objToArray.js

function isObject(arg) {
  return typeof arg === 'object' && arg !== null;
}
function objToArray(obj){
  if (!isObject(obj) || Array.isArray(obj)) throw new SyntaxError('Give me an object to work with plz. kthxbai.');
  return output = Object.keys(obj).map(function(key){
    var temp = [];
    temp.push(key);
    if (isObject(obj[key]) && !Array.isArray(obj[key])) temp.push(objToArray(obj[key]));
    else temp.push(obj[key]);
    return temp;
  });
}

//example
var d = JSON.parse('{"101":{"value":10,"text":"work! ಠ_ಠ"},"test":{"value":123,"text":"dude what"},"200":{"a":[1,2,3]},"456":{"value":9023,"text":"omg what"},"*_*":{"value":789,"text":"omgwtfbbq you cant be serious"}}');
