thanks in advance.

Can you explain the logic in detail? For example, how does [9,222,3],[9,222,4],[9,333,1] become 222_3_4 — Ian

ok, it is a good thing that the problem has been solved. If there is still a problem next time, it is better to add some examples and logic, which can speed up the solution. — Ian

You didn't explain the logic, but here is an example that will give you a good starting point for what you need and is similar to what I've understood.

let arrData = [
  [9, 222, 3],
  [9, 222, 4],
  [9, 333, 1],
  [9, 333, 2],
  [9, 444, 1]
].map((item) => {
  return `${item[1]}_${item[2]}_${item[0]}`;
}).join('/');

console.log(arrData);
