Assorted Thoughts on Zig and Rust

I think Zig's biggest advantage is that it's just C without the warts, or footguns as is said in the Zig world. The comptime feature is probably the most exciting thing I've seen in a while. I've looked at Rust and feel it's more of a competitor to C++, Java and C#. Whereas Zig is C done right.

I'm not entirely sure I've heard anyone express this before. What do you like about it?

Rust and Zig target different audiences though. It's often been said before, but Rust is mainly a C++ replacement, while Zig is mainly a C replacement. I have switched from C++ as my default-language to C a few years ago, and having dabbled a bit in both, I feel a lot more attracted to Zig than Rust for future projects (and mostly for the same reasons why I switched from C++ to C).

If Zig can settle in the niche that C is used for today (including "nearby" areas where C programmers consider switching to a higher-level language), then it is already a great success. I think (rather: hope) what we will see in the future is that no single language will dominate certain fields anymore like it was the case in the 90's and early 00's.

Rust doesn't need to fit into every niche, and it would be harmful to bend Rust in a way that it fits everywhere. It would end up as a "kitchen-sink language" with tons of competing concepts and ideas. This is exactly what's currently killing C++.

Never underestimate the importance of aggressive marketing and sales around tools for software developers. Even OSS projects need clever sales pitches and visibility to become successful. Mozilla had the resources to pull that off for Rust.

Multiple points:

I really like how there's a package for everything. Many other languages have adopted this method, but for example in Rust, most packages are not as mature as JS packages are. The JS ecosystem is responsible for spawning services that fund Open-Source developers. Packages are also easy to install. I spent a whole weekend trying to install Postgres and Drogon (a http server) on C++ with conan/vcpkg, and in the end I could only manage with a docker container installing these dependencies via apt-get, which was exactly what I did not want.

Furthermore, NPM is the package manager among package managers. No other package manager comes close. Python has too many options, virtual environments and so on. Rust's cargo is good enough, but I really do not enjoy having to install a seperate package (cargo-edit) just to add a package via the command line instead of editing text files. C++'s package management systems are most of the time a total letdown or don't have widespread adoption. Not only that, npm also takes care of a package maintainer needs (semver, transitive dependencies, etc)

Many people express dissatisfaction about build tools and the like, but as someone who got into webdev at the exact time people began building larger applications on the client, I love them. Sure, when they first appeared they were a pain to work with, but most modern build systems are amazing. I can just include most files (MD, SVG, images) and work with as if they were JSON/JS files and don't have to worry about how it's done internally.

Prototyping is really fast and important if you work with startups or want to create a proof of concept for a customer. I can throw together a functioning backend with http server and database in a couple of days.

Modern JS frameworks are uncomplicated and can be minimal if you know how to use them. For example, my personal site (https://juliankrieger.dev/) is written in Gatsby and React.js, but it weighs only 20kb. Now, there's not much on it but all content is rendered server side and only rehydrated when I need it. For anyone interested in getting even better results on a personal homepage, I recommend looking at 11ty for a static site generator and htm/preact for an absolutely minimal React implementation that only ships javascript where you really need it.

I also like how it enables me to write scripts for personal use and at the same time I can use Node for larger projects. I've used python for this in the past, but a large python code base can be a beast of its own.

Moreover, not having to recompile dependencies on a code change is a welcome feature. My main problem with Rust are the large compile times. Node even enabled me to hot reload code under the right conditions, making iterative development an insanely fast process.
