javascript - remove item from array using its name / value

Question

I have the following array

var countries = {};

countries.results = [
    {id:'AF',name:'Afghanistan'},
    {id:'AL',name:'Albania'},
    {id:'DZ',name:'Algeria'}
];

How can I remove an item from this array using its name or id ?

Thank you

Created a handy function for this..

function findAndRemove(array, property, value) {
  array.forEach(function(result, index) {
    if(result[property] === value) {
      //Remove from array
      array.splice(index, 1);
    }    
  });
}

//Checks countries.result for an object with a property of 'id' whose value is 'AF'
//Then removes it ;p
findAndRemove(countries.results, 'id', 'AF');
