Underscore JS - Sorting an Array of Objects

Question

I have an array made up of 80 individual objects. Within those individual objects I have a key: value pair. The key is "number" and values go from "0001" to "0080".

So the structure would be something like

 myArray = [{number: "0001"}, {number: "0002"}, {number: "0003"} ]

and so on...

I'm using Underscore, but I'm having trouble figuring out a way to order the individual objects so they're sorted 1,2,3,5. The values that are number are also strings.

Any suggestions?

That's invalid syntax. Can you show us what kind of objects you really have in JSON? — Bergi

Looks like that key is useless and you should just go for _.pluck(…, "number") before sorting. — Bergi

Use sortBy function:

var myArray = [{number: "0003"}, {number: "0001"},{number: "0002"} ];
var result = _.sortBy(myArray, "number");
console.log(result);

<script src="http://underscorejs.org/underscore.js"></script>

results in:

[{number: "0001"}, {number: "0002"},{number: "0003"} ]
