JavaScript Set
It is a collection of values that can be accessed without a specific key. The elements are unique and the addition of duplicates is not allowed. Sets are mostly used to remove duplicates from any other data structure
Syntax:
new Set([it]);
Example: In this example, we will learn how to implement a set
Javascript
let sample = new Set(); sample.add( "Hello" ); sample.add(1) sample.add( "Bye" ) sample.add( "@" ); for (let item of sample) { console.log(item); } |
Hello 1 Bye @
Set vs Map in JavaScript
In JavaScript, Set and Map are two types of objects that are used for storing data in an ordered manner. Both these data structures are used to store distinct types of data inside the same object. In Maps, the data is stored as a key-value pair whereas in Set data is a single collection of values that are unique.
Let’s learn about the uses of these two data structures.
