The Underscore js Way

Which is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

Solution:

var data = {
 code: 42,
 items: [{
 id: 1,
 name: 'foo'
 }, {
 id: 2,
 name: 'bar'
 }]
};
var item = _.findWhere(data.items, {
 id: 2
});
if (!_.isUndefined(item)) {
 console.log('NAME =>', item.name);
}
//using find - 
var item = _.find(data.items, function(item) {
 return item.id === 2;
});
if (!_.isUndefined(item)) {
 console.log('NAME =>', item.name);
}
