Examples

Using the delete method

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.

// Delete any point with `x > 10`.
setObj.forEach(function(point){
  if(point.x > 10){
    setObj.delete(point)
  }
})
