• defer is used to ensure something runs when the context exits

Performance

• https://youtu.be/U248O0cN5iE
• Use structs over classes (classes use heaps, structs and values use stack)
• Use structs over concatenated strings (structs offer better memory management)
• Any reference requires a heap, so values are much better as they use stack
• Strings and classes store their contents on the heap
• Enums that use strings are still better than just strings by themselves
• To use static dispatch over dynamic dispatch:
  • Use final for classes (unless they are intended to be extended)
  • Avoid using classes when structs or protocols will do
  • If a class just defines an interface for future classes, it should be a protocol
  • Class inheritance structures can probably be struct and protocol structures instead
  • Structs and classes can both use protocols, not just classes, but structs too
• Questions to always ask yourself:
  1. Is this going to be allocated to the stack or the heap
  2. When I pass this instance around, how much reference counting am I going to incur?
  3. When I call a method on this method on this instance, is it going to be statically or dynamically dispatched?
