Remove object from array if it is contained in another array

ecmascript-6, javascript

Solution

Not very optimal, but try this

array = array.filter( function( item ){
  return array2.filter( function( item2 ){
    return item.Email == item2.Email;
  }).length == 0;
});

Try with `find` as well, it won't iterate all the elements and will break after first match itself

array = array.filter( function( item ){
  return array2.find( function( item2 ){
    return item.Email == item2.Email;
  }) == undefined;
});

Problem

I am trying to remove an object from an array, if that object's property (unique) is included in the other array. I know I can do a nested for-loop like this: ``` for(i = 0; i < array.length; i++) { for(j = 0; j < array2.length; j++) { if(array[i].Email === array2[j].Email) { //remove array[i] object from the array } } } ``` Or whatever. Something like that. Is there an ES6 filter for that? I can easily do a filter up against a regular array with strings, but doing it with an array of objects is a bit more tricky.
