Array versus linked-list

  • It’s easier to store data of different sizes in a linked list. An array assumes every element is exactly the same size.
  • As you mentioned, it’s easier for a linked list to grow organically. An array’s size needs to be known ahead of time, or re-created when it needs to grow.
  • Shuffling a linked list is just a matter of changing what points to what. Shuffling an array is more complicated and/or takes more memory.
  • As long as your iterations all happen in a “foreach” context, you don’t lose any performance in iteration.
