We were able to assign a variable to new Set(), which creates an empty set. Then using set().add(value) we were able to add a unique list of values to a collection. Conveniently Set() returns this new list as an object. Once you have this object you are able to use forEach in order to iterate through your object and apply specific functions.
Set() also has a few other uses. You are able to delete elements from the collection in one of two ways. You can either use set().delete(value) which will return a boolean response regarding whether or not the value was deleted. Alternatively you can use set().clear in order to clear the entire collection, which will return an undefined value.
