difference < Set < JavaScript

New, not-widely-supported method 1/24. The difference() method of a Set takes a set and returns a new set containing elements in this set but not in the given set.

    
    const odds = new Set([1, 3, 5, 7, 9]);

    const squares = new Set([1, 4, 9]);

    const oddsDifferenceSquares = odds.difference(squares);

    console.log(odds.difference(squares));
    // Set(3) { 3, 5, 7 }
