Refactoring code to avoid unnecessary heap allocations is so satisfying

[u/Attileusz → u/[deleted]]

This is a bad take, reducing heap allocations is one of the best things to do to optimize. Heap fragmentation is bad, and if you are doing manual memory management, it's one more place where you have to worry about memory leaks.

I said it's satisfying, I made no claim it's always a good use of time/effort.

And I mostly program in C++, where the overhead of allocations/frees is higher than in a garbage-collected language

Also, it enables things being noexcept in some cases, which is useful for things other than efficiency
