![]() The following examples will show how to use a set to store a user’s entered data for a hypothetical video game. Let’s look at some examples of how you can create a new set in your programs. JavaScript sets can contain any number of items in any data type. Now that you have some background information on sets and their place in the Javascript world, let's look at some examples and discuss how you can use sets in your programming. Primitive data types are frequently used as items within data collections as they are used to document types of information and their values. The only things in JavaScript that are not objects are the primitive data types - null, undefined, strings, numbers, boolean, and symbols. Meaning, almost everything in it are objects, including sets. JavaScript is an object-oriented programming language. ![]() In the case of adding duplicate and equal items, only the first instance will be saved to the set. Sets can hold data of any type, but may not contain duplicate items. Sets are data objects that hold a collection of unique values. Like any other object in JavaScript, there are rules about how sets function and how they are used. If you aren't familiar with JavaScript you should check out our post on the basics of JavaScript. One of those ways is the JavaScript object known as sets, which is used specifically on data collections. JavaScript is a powerful programming language that offers a variety of ways to manage data and collections of data. ![]() Without any further delay, let’s jump right into the meat of this post. Furthermore, we will look at the methods that manipulate and modify the set object during development. We will also cover how it works and how to use it in your programs or software. In this post, we will discuss the benefits of the JavaScript set object and how to use it. ![]()
