1 Get Random Item from Set

In this example,

We create a Set named mySet containing elements.
We convert the Set to an array using the spread operator [...mySet].
We generate a random index within the range of the array's length using Math.random().
We retrieve the random item from the array using the random index.
Finally, we log the random item to the console.

TypeScript Program

let mySet: Set<string> = new Set(['Apple', 'Banana', 'Orange', 'Mango']);
let myArray: string[] = [...mySet];
let randomIndex: number = Math.floor(Math.random() * myArray.length);
let randomItem: string = myArray[randomIndex];
console.log('Random item from set:', randomItem);

Output

Random item from set: Mango
