"Coming-from" language tips

[Sobeston]

Recently added support for custom show/hide admonitions for other programming languages.

Here's one found on the Slices page:

Occasional narrow comparisons for other languages, or additional context for people coming from specific languages, may be very useful for some. Feel free to suggest more in this issue.

• Go

  • [X] slices: comparison

• C++

  • [X] arraylist: ~= std::vector
  • [ ] comptime: vs constexpr/consteval
  • [ ] errors: vs exceptions

• JS

  • [X] assignment: "undefined" isn't the same

• C

  • [ ] comptime: comptime vs macros / converting macros to comptime
  • [ ] single-item pointers: strictly single-item
  • [ ] imports: vs include / note on code guards & circular references
  • [ ] allocators: compare with c_allocator and malloc/free

• Rust

  • [ ] switches: comparison with match
  • [ ] enums: comparison
  • [ ] errors: comparison
  • [ ] optionals: comparison

I don't know if you want to add to this guide, how to create basic custom allocator, like c_allocator/raw_c_allocator (more simple) - using std.mem.Allocator.

The example below shows a minimal version of both interfaces for custom allocators.

• C++17 (std::pmr::memory_resource),
• Rust (std::alloc::GlobalAlloc)
