What’s a good way to check if two arrays are equal in JavaScript?

Definitely! If you want a quicker solution and the arrays only contain simple data (like numbers or strings), you can use a more compact method with JSON.stringify. Here’s how you can do it:

function arraysEqual(arr1, arr2) {
  return JSON.stringify(arr1) === JSON.stringify(arr2);
}

It’s a good shortcut for prototyping and works fine when you’re just comparing simple arrays. Just keep in mind that it can be slow with large arrays and depends on the order of elements, so it’s not always the most efficient."
