Add distinct items to an array in angularjs

Question

I'm trying to add to an array distinct item but this error appears "ReferenceError: $ is not defined" any help

function unique(list) {
  var result = [];
  $.each(list, function(i, e) {
    if ($.inArray(e, result) == -1) result.push(e);
  });
  return result;
}

Use angular.forEach instead of $. Otherwise include jQuery libray. — Dinesh ML

It seems you didn't load jQuery.
Btw to implement this function you don't need that.

Try this:

function unique(list) {
    var result = [];

    for (var i = list.length - 1; i >= 0; i--) {
        if (result.indexOf(list[i]) == -1) {
            result.push(list[i]);
        }
    };

    return result;
}

If you did load JQuery in your, have you defined it as $?

You can use Array.forEach and

Array.indexOf to solve your problem.

SO does not allow me for more that two links. but you can use the ES6 array.find function to do the same job
