How to create a Set of size N in JavaScript ?

Answer

To create a set of size N in JavaScript, you can use a loop to add elements to a Set object until it reaches the desired size.

✐ Examples

1 Create a Set of Size N with Sequential Numbers

In this example,

We define a function named createSetOfSizeN that takes an integer n as a parameter. This parameter represents the desired size of the set.
Inside the function, we create a new Set object named set.
We use a for loop to add integers from 1 to n to the set using the add method of the Set object.
The function returns the created set.
We call createSetOfSizeN with a specific size (e.g., 5) and store the result in a variable named mySet.
Finally, we log the created set to the console using console.log.

JavaScript Program

function createSetOfSizeN(n) {
    let set = new Set();
    for (let i = 1; i <= n; i++) {
        set.add(i);
    }
    return set;
}

let mySet = createSetOfSizeN(5);
console.log(`Created set of size 5 with sequential numbers: ${JSON.stringify(Array.from(mySet))}`);

Output

Created set of size 5 with sequential numbers: [1,2,3,4,5]

2 Create a Set of Size N with Random Numbers

In this example,

We define a function named createRandomSetOfSizeN that takes an integer n as a parameter. This parameter represents the desired size of the set.
Inside the function, we create a new Set object named set.
We use a while loop to add random numbers to the set until it reaches the desired size. The Math.random() function generates a random number between 0 (inclusive) and 1 (exclusive).
The function returns the created set.
We call createRandomSetOfSizeN with a specific size (e.g., 5) and store the result in a variable named myRandomSet.
Finally, we log the created set to the console using console.log.

JavaScript Program

function createRandomSetOfSizeN(n) {
    let set = new Set();
    while (set.size < n) {
        let randomNumber = Math.floor(Math.random() * 100) + 1; // Generate random number between 1 and 100
        set.add(randomNumber);
    }
    return set;
}

let myRandomSet = createRandomSetOfSizeN(5);
console.log(`Created set of size 5 with random numbers: ${JSON.stringify(Array.from(myRandomSet))}`);

Output

Created set of size 5 with random numbers: [35,57,18,91,74]
