indexOf method in an object array?

Question

What\'s the best method to get the index of an array which contains objects?

Imagine this scenario:

var hello = {
    hello: \'world\',
    foo: \'ba         


        

Answer 1

array.filter(function(item, indx, arr){ return(item.hello === 'stevie'); })[0];

Mind the [0].

It is proper to use reduce as in Antonio Laguna's answer.

Apologies for the brevity...
