What is the equivalent method in Angular 2 of Angular $.grep() method?

Question

How can I refactor this code using angular 2 methods? I could not find anything on google.

var tooltipsData = $.grep(tooltips, function (element, index) {
    return (element.ProductCode == ProductCode);
});

Answer 1

Looks like what you really are trying to do is implement that without jQuery (Angular 2 is still just JavaScript (or TypeScript)). If you are trying to implement it in JS, use the Array.filter function

var tooltipsData = tooltips.filter(function (element, index) {
   return (element.ProductCode === ProductCode);
});
