> While disabling GC is an option, writing your code in a way that doesn’t require GC to run much (if at all) by reducing allocations in the first place, is as good as managing memory manually with `malloc` et al.

Data structures often allocate without user control, so this may be hard to achieve in many cases. For instance, in Julia I cannot fill a Dict using a preallocated backing buffer; other languages make this easier.

Another example is that `view`s can allocate without user approval and hurt performance [[RFC/ANN] Restacker.jl: A workaround for the heap-allocated-immutable problem?](https://discourse.julialang.org/t/rfc-ann-restacker-jl-a-workaround-for-the-heap-allocated-immutable-problem/35037).
