C was and continues to be the best language for implementing a software library like SQLite. There are no plans to recode SQLite in any other programming language at this time.
Why SQLite is implemented in C and not C++, Java, or a safe language (undated page, last updated 2025-05-09)
Most of the code I write is in C++, although I've written fair amounts of code in Java, Python, Perl, Self, Cecil, x86 assembly, and Pascal over the years.

C++ instead of Zig would be a reasonable choice for Bun. We would get constructors & destructors. We could delete lots of extern "C" wrapper code. But, we would still be reliant on style guides enforced through code review, and even with ASAN, memory corruption and memory leaks would still happen.

This makes a memory-safe programming language like Rust a compelling addition to Mozilla's tool-chest for protecting against potentially malicious media content on the Web.

While it seemed promising, one of the problems for us with Parcel's watcher is that it's written in C++, and in turn requires a full C++ toolchain to build.

The ergonomics of C++ are also simply not good - header files are annoying, templates are complicated, you can easily cause a compile error that throws pages of overloads in the standard library at you.

Every entry is a verbatim quote and a link to the public post it came from. Nothing is paraphrased. If it is not on record somewhere public, it is not here.
The verdict is what they actually said: loved and liked are explicit; recommended means they told others to get it; uses means they only say they use it; read is a book on their public shelf with no verdict; mixed and disliked are kept too.
A dashed affiliate link, sponsored or their own label means the post disclosed a relationship. It is shown, never hidden.
The shading behind a date shows how dated a recommendation is for its kind of thing.
The shading behind a date shows how dated a recommendation is, for its kind of thing. Fully green is recent. It drains a quarter at a time as the post gets older, and is empty once it reads as dated.
What counts as old depends on the thing. A laptop praised four years ago has been replaced twice; a book loved twenty years ago is probably still loved. The shading is gone after about:
Stripes mean the post carries no date and the date shown is an estimate. No date at all, no shading.
