Convert objects to array in javascript

Question

I really want to convert a object to array but my codes doesn’t worked.

data = "errors": {
  "user": {
    "name": "empty"
  },
  {
    "length": "exceeds"
  },

  "title": {
    "name": "empty"
  },
  {
    "length": "exceeds"
  }
}

Now I want to make them:

data = ["empty", "exceeds", "empty", "exceeds"];

What I’ve done so far is:

var arr = Object.keys(data[i].data.errors).map(function(k) {
  return data[i].data.errors[k]
});

console.log(arr);

But the output is not what I expected. Please help. Thank very much.

Please correct the code samples. JS does not support typographical quotes. — Tomalak, Jan 11 '16 at 12:09
There are more errors than just typographical quotes here. Please have a look at this: http://www.sscce.org/ — Denys Séguret, Jan 11 '16 at 12:12
I just removed now the typographical quotes and changed to "". — qazzu, Jan 11 '16 at 12:12
`But the output is not what I expected` - no, you wouldn't be getting **any** output, except errors in the console — Jaromanda X, Jan 11 '16 at 12:13
what is that array supposed to represent? what does "empty" mean? It's not clear what your trying to achieve or why. — Liam, Jan 11 '16 at 12:15
Here is what it should look like { "errors":{ "user":{ "name" : "empty", "length" : "exceeds" }, "title":{ "name" : "empty", "length" : "exceeds" } } } — gcoleman0828, Jan 11 '16 at 12:20

If you always know the keys of the inner objects are going to be name and length a short way might be:

var out = Object.keys(data.errors).reduce(function (p, c) {
  return p.concat([data.errors[c].name, data.errors[c].length]);
}, []);
