Odin is a manually memory managed language. Beginners of such languages are often afraid of memory leaks, meaning that you forget to deallocate memory. The first remedy for this is to use the tracking allocator. It will warn you about memory you forgot to deallocate. Nifty! But you can also think along these lines: Can I simplify things a bit, so I don’t have to think about the deallocation? What you can do is to try to use the temporary allocator whenever possible.
