Filter allows you to narrow down the results of a collection that match a certain criteria
var records = [
{Id: 1, Active: true},
{Id: 2, Active: false},
{Id: 3, Active: true}
];
var activeRecords = records.filter(function(rec){
if(rec.Active){
return rec;
}
});
//console.log(activeRecords) ==> [{Id: 1, Active: true},{Id: 3, Active: true}]
