JavaScript: Tips of the Day

Returns the symmetric difference between two arrays, after applying the provided function to each array element of both

Example:

const tips_symmetricDifference = (x, y, fn) => {
  const sA = new Set(x.map(v => fn(v))),
    sB = new Set(y.map(v => fn(v)));
  return [...x.filter(x => !sB.has(fn(x))), ...y.filter(x => !sA.has(fn(x)))];
};

console.log(tips_symmetricDifference([3.5, 5.5], [5.5, 7.5], Math.floor));

Output:

[3.5, 7.5]
