--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.

--hints--

Your Set should contain the values 1, 3, & 4

assert(
  (function () {
    var test = checkSet();
    return test.has(1) && test.has(3) && test.has(4) && test.size === 3;
  })()
);

--seed--

--seed-contents--

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

--solutions--

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