Javascript Arbitrary sort array based on values of a field

So I have an array of object which looks like this:

var myArray = [{priority : "low"}, {priority: "critical"}, {priority: "high"}]


I need to sort in this way: 1)Critical, 2) High and 3) Low.

how can this be done?

Answer

Use an object that maps priority names to numbers, then sort based on that.

var priorities = {
  low: 0,
  high: 1,
  critical: 2
};

var myArray = [{
  priority: "low"
}, {
  priority: "critical"
}, {
  priority: "high"
}]

myArray.sort(function(a, b) {
  return priorities[b.priority] - priorities[a.priority];
});

console.log(myArray);
