Question

How to insert an element in a set with TypeScript

Answer 1

// Create a new Set
const mySet: Set<unknown> = new Set();

// Add elements to the Set
mySet.add(1);
mySet.add(2);
mySet.add(3);
mySet.add(4);
mySet.add(5);

// Attempt to add a duplicate element
mySet.add(2); // No effect, as 2 is already in the Set

console.log(mySet);


/*
run:

Set (5) {1, 2, 3, 4, 5} 

*/
