ES6 Set Operations: Intersection, difference, Union, Subset
In this video, we'll learn about the set operations intersection, difference, and union in ES6. We'll start by defining what a set is, and then we'll see how to use the set operations to manipulate sets.
What is a Set?
A set is a collection of unique elements. In ES6, sets are represented by the `Set` constructor. To create a set, we can use the following syntax:
The `Set` constructor takes an array of elements as its argument. The elements in the set are unique, so if we add an element to the set that is already in the set, the element will not be added.
Set Operations
There are three main set operations: intersection, difference, and union.
*Intersection* returns a new set that contains the elements that are common to both sets.
*Difference* returns a new set that contains the elements that are in the first set but not in the second set.
*Union* returns a new set that contains all of the elements in both sets.
We can use the set operations to perform a variety of tasks, such as finding the common elements between two sets, finding the elements that are unique to a set, and merging two sets together.
