in B but not in A

[ptt.bds]

I have 2 lists, A and B, and I want to create a list that includes the values that are in B but not in A.
Please guide me

Easy.

Foreach [[LIST_B]]
_ Contains Variable with list: [[LIST_A]] Value: [[FOREACH_DATA]]
_ If [[LIST_CONTAINS]] == true
_ _ Delete By Value Variable with list: [[LIST_B]] Value: [[FOREACH_DATA]]

function valuesInBNotInA(A, B) {
  // Use the filter method to create a new array with values from B that are not in A
  const result = B.filter(value => !A.includes(value));

  return result;
}

// Example lists A and B
const listA = [1, 2, 3, 4];
const listB = [3, 4, 5, 6];

// Call the function to get the values in B not in A
const valuesNotInA = valuesInBNotInA(listA, listB);
console.log(valuesNotInA); // Output: [5, 6]

@DuckDuck The tool only returns a true or false value, and I need to find out the different lists."
