[removed] filter array of objects by array of strings

Question

I wonder if there is a more elegant way of doing this. Suppose i have an array of objects like this:

a = [
  {
    \"id\": \"kpi02\",
    \"value\": 10
  },
         


        

Answer 1

Just make use of Array.indexOf

var b = a.filter(function(item){return kpids.indexOf(item.id) > -1 });

Array.indexOf returns the index of the argument passed in the array on which indexOf is being called on. It returns -1 if there isn't the element which we are looking for.

So, we make sure that it index is greater than -1
