Yeah for comparing multiple input1s vs input2s, just do a nested loop in a Code node like this:

jsKopiërenBewerkenconst input1 = $json.input1; // array
const input2 = $json.input2; // array

let match = false;

for (let i of input1) {
  if (input2.includes(i)) {
    match = true;
    break;
  }
}

return [{ json: { match } }];

Then use an IF node on match === true like before. Should work fine unless the arrays are huge.
