How can I find the index of an object inside a Array using underscore.js?

Question

I want to get the index of the given value inside a Array using underscore.js.

Here is my case

var array = [{\'id\': 1, \'name\': \'xxx\'},

Underscore uses native indexOf method if available,else applies fallback. Thus, for a list of objects you have to implement it in some other way.

One example could be

_.chain(array).pluck("key").indexOf("value").value();

or

_.map(array,function(e) { return e.key; }).indexOf(value);
