Description

Let's practice removing items from an ES6 Set using the delete method. First, create an ES6 Set: var set = new Set([1,2,3]); Now remove an item from your Set with the delete method.
set.delete(1);
console.log([...set]) // should return [ 2, 3 ]

Instructions

Now, create a set with the integers 1, 2, 3, 4, & 5. Remove the values 2 and 5, and then return the set.

Tests

tests:
  - text: Your Set should contain the values 1, 3, & 4
    testString: assert((function(){var test = checkSet(); return test.has(1) && test.has(3) && test.has(4) && test.size === 3;})());

Challenge Seed

function checkSet(){
   var set = null;
   return set;
}

Solution

function checkSet(){
var set = new Set([1,2,3,4,5]);
set.delete(2);
set.delete(5);
return set;}
