How to Convert a Set of Strings to a Set of Integers in TypeScript - Step by Step Examples
How to Convert a Set of Strings to a Set of Integers in TypeScript ?
Answer
In TypeScript, 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,
- We have a Set named stringSet1 containing the elements '1', '2', '3', '4', '5'.
- We convert each element of stringSet1 to an integer using the map() function along with parseInt() method.
- We create a new Set named intSet1 containing the converted integers.
- We print the resulting intSet1 to the console.
TypeScript Program
const stringSet1: Set<string> = new Set(['1', '2', '3', '4', '5']);
const intSet1: Set<number> = 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,
- We have a Set named stringSet2 containing the elements '10', '20', '30', '40', '50'.
- We convert each element of stringSet2 to an integer using Array.from() and parseInt() method.
- We create a new Set named intSet2 containing the converted integers.
- We print the resulting intSet2 to the console.
TypeScript Program
const stringSet2: Set<string> = new Set(['10', '20', '30', '40', '50']);
const intSet2: Set<number> = 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 }
