This ensures that data passed into our function cannot be mutated, which is something we may want to protect against when using pass-by-reference, to ensure we can efficiently pass data into a function, without the worry that it will be modified. ►YouTube Channel: https://www.youtube.com/c/MikeShah ►Please like and subscribe to help the channel!
