Array.prototype.filter() expects a value to be returned at the end of arrow function array-callback-return

Question

I've seen similar questions here, but I can't quite figure out how to silence this error for my case with several conditions involved.

This is the .filter() object:

orders.filter((order) => {
  if (filterId === 0) {
    return order.status === 0 && order.type <= 3;
  } else if (filterId === 1) {
    return order.status === 0 && order.type === 0;
  } else if (filterId === 2) {
    return order.status === 0 && order.type === 1;
  } else if (filterId === 3) {
    return order.status === 0 && order.type === 2;
  }
}).map(...);

consider switch your approach to switch instead chain of if else.

 orders.filter((order) => { let value = 0; switch(filtedId){ case 0: value = order.status === 0 && order.type <= 3; case 1: value = order.status === 0 && order.type === 0; case 2: value = order.status === 0 && order.type === 1; case 3: value =order.status === 0 && order.type === 2; default: value = 0 } return value }).map(...);
