The best way to turn a json object into array
Many discussions about this problem. Here is what we use without jQuery:
var characters={
charlie:'Charlie Brown',
lucy:'Lucy van Pelt',
linus:'Linus van Pelt'
};
var output=[];
for (var key in characters) {
if (characters.hasOwnProperty(key)) {
output.push(characters[key]);
}
}Note there is a hasOwnProperty check to filter out other keys in the json object.
If jQuery is available, please see a pro-tip in the comments section provided by cloze.

You can do this in a single $.map().
var array = $.map(_elements, function(el) {
return [[el.Name, el.Age, el.ID]];
});
</code>
The double brackets keep $.map() from flattening the array.
Of course we have more tools with jQuery available. This piece of pro-tip realizes the function with JavaScript only.
But thanks for the input.
