how to check if two sets are disjoint in javascript

To check if two sets are disjoint in JavaScript, we can convert the Set objects to arrays and use the some method to check if any element in the first set is included in the second set. If there is a match, then the sets are not disjoint.

Here's an example implementation:

index.tsx
function areSetsDisjoint(set1, set2) {
  return !Array.from(set1).some(element => set2.has(element));
}

This function takes two Set objects as parameters and returns true if they are disjoint or false otherwise.

We can use this function as follows:

index.tsx
const set1 = new Set([1, 2, 3]);
const set2 = new Set([4, 5, 6]);
const set3 = new Set([3, 4, 5]);

console.log(areSetsDisjoint(set1, set2)); // Output: true
console.log(areSetsDisjoint(set1, set3)); // Output: false

In the first example, set1 and set2 are disjoint because there are no common elements between them. In the second example, set1 and set3 are not disjoint because they both contain the element 3.
