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

Not that I'm aware of. Still, you can do it yourself fairly concisely:

var obj = { a: 1, b: 2, c: 3 };
var arr = [];
for (var i in obj) {
   var e = {};
   e[i] = obj[i];
   arr.push(e);
}
console.log(arr);
// Output: [Object { a=1 }, Object { b=2 }, Object { c=3 }]

Of course, you can't alert this either, so you might as well just console.log(obj) in the first place.

You could output arrays of arrays:

var obj = { a: 1, b: 2, c: 3 };
var arr = [];
for (var i in obj) {
   arr.push([i, obj[i]]);
}
console.log(arr);
// Output: [["a", 1], ["b", 2], ["c", 3]]

alert(arr);
// Alert: a, 1, b, 2, c, 3

But, again, ew.
