Using a argument as a property key

Question

Lets say I got this function:

  vm.setSelectedItem = function(itemName, searchedItems){
    vm.selectedItem = _.findWhere(searchedItems, {name: itemName});
  };

I need to make the "name" dynamic

  vm.setSelectedItem = function(itemName, searchedItems, propertyKey){
    vm.selectedItem = _.findWhere(searchedItems, {}); //How do I use the arg propertyKey here?
  };

How do I do this?

Try:

  vm.setSelectedItem = function(itemName, searchedItems, propertyKey){
    var obj = {};
    obj[propertyKey] = itemName;
    vm.selectedItem = _.findWhere(searchedItems, obj);
  };

or, in ES6: `var obj = { [propertyKey]: itemName }` – Alnitak Jan 15 '16 at 09:22
with due respect, isn't this identical to answer I had posted? – gurvinder372 Jan 15 '16 at 09:23
