How to Convert Array to Set in JavaScript?
The task is to convert a JavaScript Array to a Set with the help of JavaScript. We are going to discuss a few approaches:
Approach:
- Take the JavaScript array into a variable.
- Use the new keyword to create a new set and pass the JavaScript array as its first and only argument.
- This will automatically create the set of the provided array.
Example 1: In this example, the array is converted into a set using the same approach defined above.
Javascript
let A = [1, 1, 2, 2, 2, 2, 5, 5];function GFG_Fun() { let set = new Set(A); console.log(JSON.stringify([...set]));}GFG_Fun(); |
Output
[1,2,5]
Example 2: In this example, the array is converted into set using a bit approach than above.
Javascript
let Arr = ["A", "A", "Computer Science", "portal", "for", "for", "Geeks", "Geeks"];function GFG_Fun() { let set = new Set(Arr); console.log(JSON.stringify([...set.keys()]));}GFG_Fun(); |
Output
["A","Computer Science","portal","for","Geeks"]
