Simulating the intersection operation

To simulate the intersection operation, we can also create a function to help us create a new set of the common elements that both setA and setB demonstrated as follows:

const intersection = (set1, set2) => {  const intersectionSet = new Set();  set1.forEach(value => {    if (set2.has(value)) {      intersectionSet.add(value);    }  });  return intersectionSet;};console.log(intersection(setA, setB)); // {2, 3}

The preceding code does the same thing as the intersection function we developed, however, the preceding code is not optimized (as we also developed an optimized version).
