How to find the intersection of two sets (values that exist in both sets) in Node.js

Answer 1

function getIntersection(set1, set2) {
  const intersection = new Set(
    	[...set1].filter(element => set2.has(element))
  );

  return intersection;
}

const set1 = new Set(['typescript', 'javascript', 'node.js', 'python']);
const set2 = new Set(['typescript', 'javascript', 'node.js', 'c#']);

const intersection = getIntersection(set1, set2);  

console.log([...intersection].join(' '));
  
  
  
/*
run:
  
typescript javascript node.js
  
*/
