Find object by its property in array of objects with AngularJS way

How about plain JavaScript? More about Array.prototype.filter().

var myArray = [{'id': '73', 'name': 'john'}, {'id': '45', 'name': 'Jass'}]

var item73 = myArray.filter(function(item) {
  return item.id === '73';
})[0];

// even nicer with ES6 arrow functions:
// var item73 = myArray.filter(i => i.id === '73')[0];

console.log(item73); // {"id": "73", "name": "john"}

you can use angular's filter https://docs.angularjs.org/api/ng/filter/filter

in your controller:

$filter('filter')(myArray, {'id':73}) 

or in your HTML

{{ myArray | filter : {'id':73} }}
