Creating a set in JavaScript is achieved by utilizing the `Set` constructor. When you invoke `new Set()`, you create a set object that can hold unique values of any type, whether it's primitive values or references to objects. This is fundamental in JavaScript because it provides a collection where you can store values without duplicates, automatically ensuring that each element is unique.

The `Set` constructor allows you to also initialize the set with an iterable, making it a versatile choice for operations that require a unique collection of items. For example, you might pass an array to `new Set(array)`, which will then contain only the unique elements from that array.

Other methods of creating collections, such as array literals or defining a class, do not create sets. Arrays, for instance, can hold duplicate values and have different methods and properties compared to sets. Similarly, while you can create a class in JavaScript, this does not relate to creating a set. The use of the `new` operator with an object without the context of `Set` would merely create a standard object, not a set.

Thus, the proper and specific method to create a set in JavaScript is to utilize the `Set` constructor, ensuring you are taking advantage of
