Answer from AI

In JavaScript, to check if a field is an array, the method Array.isArray() is used:

if (Array.isArray(field)) {
  console.log('This is an array');
} else {
  console.log('This is not an array');
}

This method is reliable and accounts for all array features in JS. Alternatively, you can use instanceof Array, but it may not work correctly when working with arrays from different contexts (for example, iframe).
