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"]
