Finding the intersection of two sets

Next, we'll take a look at how to find out the elements two Sets have in common. This operation is called an intersection of two sets. An element is in the intersection of two sets, if it exists in both of them.

In this recipe, we'll see how to create an intersection of two Set instances.

Getting ready

This recipe assumes that you already have a workspace that allows you to create and run ES modules in your browser. If you don't, refer to the first two chapters.

Harrison

Harrison

Ross Harrison discovered programming while he was an undergraduate at the University of Nebraska-Lincoln. His first programming class was a MATLAB class that was required for mechanical engineering. Despite bombing the class, he decided that it was a lot more fun than looking at CAD. He switched to computer science the next semester and never looked back. He has worked as a software engineer for over 10 years. Most of that time has been spent creating tools for digital publishers.
