Flatten object to array?

Question

I\'m using an object as a hash table. I\'d like to quickly print out its contents (for alert() for instance). Is there anything built in to convert a hash into

Answer 1

Maybe a little late, but here you have my version of the answer, updated to ES2015. I use a recursive function and it works even if there are other objects inside the main object:

function objectFlattener (object) {
  return Reflect.apply(Array.prototype.concat, [], Object.keys(object).map(key => {
    if (object[key] instanceof Object) {
      return objectFlattener(object[key]);
    }
    return `${ key }: ${ object[key] }`;
  }));
}

So changing the last return you can format the element inside your array.
