Required. The value of the element to remove from the Set object.

Return value

Using the delete method

var mySet = new Set();

mySet.delete("bar"); // Returns false. No "bar" element found to be deleted.
mySet.delete("foo"); // Returns true.  Successfully removed.

mySet.has("foo");    // Returns false. The "foo" element is no longer present.

Let's checkout below how to delete an Object from a Set.


var setObj = new Set(); // Create a New Set.

setObj.add({x:10,y:20}); // Add object in the set.

setObj.add({x:20,y:30}); // Add object in the set.

setObj.forEach(function(point){ if(point.x>10){setObj.delete(point)} }) // Delete an object from a Set.
