📝The slice method can be used to copy an entire array by specifying the start and end indices as the same values.
✨The spread operator can also be used to copy an array by spreading out the elements of the original array into a new array.
🔁Shallow copying an array only creates a new array with references to the objects or arrays within the original array.
🔑When an array contains nested arrays or objects, deep copying is necessary to ensure independent copies of all elements.
⚠️Using methods like slice and spread operator may not work for deep copying, as they only create shallow copies of nested arrays or objects within the array.
