How to Convert a Set of Strings to a Set of Integers in JavaScript


How to Convert a Set of Strings to a Set of Integers in JavaScript ?

Answer

In JavaScript, you can convert a set of strings to a set of integers by using the map() function along with the parseInt() method.



✐ Examples

1 Convert a Set of Strings to a Set of Integers using map() and parseInt()

In this example,

  1. We have a Set named stringSet1 containing the elements '1', '2', '3', '4', '5'.
  2. We convert each element of stringSet1 to an integer using the map() function along with parseInt() method.
  3. We create a new Set named intSet1 containing the converted integers.
  4. We print the resulting intSet1 to the console.

JavaScript Program

const stringSet1 = new Set(['1', '2', '3', '4', '5']);
const intSet1 = new Set([...stringSet1].map(str => parseInt(str)));
console.log('Converted int set:', intSet1);

Output

Converted int set: Set(5) { 1, 2, 3, 4, 5 }

2 Convert a Set of Strings to a Set of Integers using Array.from() and parseInt()

In this example,

  1. We have a Set named stringSet2 containing the elements '10', '20', '30', '40', '50'.
  2. We convert each element of stringSet2 to an integer using Array.from() and parseInt() method.
  3. We create a new Set named intSet2 containing the converted integers.
  4. We print the resulting intSet2 to the console.

JavaScript Program

const stringSet2 = new Set(['10', '20', '30', '40', '50']);
const intSet2 = new Set(Array.from(stringSet2, str => parseInt(str)));
console.log('Converted int set:', intSet2);

Output

Converted int set: Set(5) { 10, 20, 30, 40, 50 }
