When comparing Zig vs Racket, the Slant community recommends Zig for most people. In the question“What are the best (productivity-enhancing, well-designed, and concise, rather than just popular or time-tested) programming languages?” Zig is ranked 18th while Racket is ranked 20th. The most important reason people chose Zig is:
It's safer than C, at least.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Some safety
It's safer than C, at least.
Pro C Interop
Zig programs can import C libraries and export header files to be used in C programs.
Pro Performance
Zig is pretty fast, in some cases even faster than C.
Pro Cross-compilation is easy
The Zig compiler can build artifacts for any Tier 3 Supported platform without additional downloads.
Pro Control flow is simple and obvious
No operator overloading, property methods, runtime dispatch, macros, etc.
Pro Small binary
Produces binary smaller than C.
Pro Compile-time execution
Zig can execute code at compile-time, allowing for more performant and readable programs.
Pro No Hidden Control flow
Zig will not do anything on your back that might slow down your program & make you loose your control over your program.
Pro Realm of Racket is an excellent entry-level guidebook
Realm of Racket teaches the big-bang approach for managing world state. It does so by walking the reader through the development of small games. There are few guidebooks that are as useful and entertaining.
Pro Racket was designed to teach functional programming from the start
Racket is based on Scheme (LISP Family) and is very similar to Clojure. So there are a ton of (). The reason it is easier to learn is that it is not trying to be "Pure" if there is even such a thing in terms of Functional Programming. The great thing about Racket is it has everything included. You get DrRacket for developing programs. You want to add a picture to your software you can insert pictures. If you want to add libraries just open the package manager. The Syntax is an opinion but it really does feel easier to see what is happening since everything is in brackets)
Racket is a really a Programming Language for making Programming Languages. So there are smaller syntax Racket called Student Racket which makes things easier to pick up.
Pro Free resources to Learn
Includes several free online books and great documentation.
Pro Great RPEL IDEA included Dr. Racket
Pro Active community
Racket has an active community of users/developers that makes it easy to get help when needed.
Pro Syntax fits to functional programming
Although syntax is different from that of mainstream languages, S-expressions are a perfect match to functional programming.
Pro Subtly encourages functional programming
Racket makes it inconvenient to pursue imperative habits while encouraging functional programming by Lisps's syntax. For example, the syntax for defining a function is almost the exact same as defining a variable. In addition, Racket has a strong set of higher-order functions built in to the language.
Pro Easily embeddable
Racket is famously embedded in the game engine underlying Naughty Dog's Uncharted and The Last of Us games, because it proved to be so easy to embed.
Cons
Con Convoluted syntax
Claims to be an improvement over C, but in this area, not really.
Con No lambdas
Missing many key and useful features other languages have.
Con Deceptively gives impression it's near being production ready
No plans to hit 1.0 until 2025 (3 years later), according to Zig Roadmap speech. Impression is given that (0.9.1) language was close to ready, when it's not.
Con Creator admits to not knowing what he's doing
Creator admits his shortcomings during Zig Roadmap speech. Very disturbing. Not a language to invest in or take seriously, outside personal experimentation.
Con No closures
Does not have closures.
Con Almost no community
Lacking in libraries and users.
Con No interfaces/traits
Features that are useful are missing, where you can find them in other languages.
Con Fundraising looks suspicious
Why do we keep seeing an overhyped unfinished alpha level language showing up everywhere? That answer looks like a financial incentive to promote the language, the Zig Software Foundation, that is making hundreds of thousands of dollars a year from donations. To aggressively maintain cash flow, it appears any opinions that goes against their narrative is suppressed, attacked, or eliminated. All while the hype machine runs rampant. That isn't a language for the people, that looks to be a cash grab for the few that will result in nothing useful. Save yourself the headache and games, better to just use C or other languages with C-like syntax, can interface with C, and are actually useful. Better to not waste your valuable time on crap like Zig, false media hype, or getting scammed.
”If it sounds too good to be true, it probably is.”
This blog has published 2 excellent articles on how Zig's claims do not live up to reality after more than 6 years of development.
Con Poor compiler errors
Several years into development, language still a mess, and no hope of fixing itself for yet more years later.
Con No standard package manager
Several years into development, and still no standard package manager is ridiculous.
Con Exhibits cult-like behavior and animosity towards other programming languages
Strange culture that bashes other languages and are not open to criticism about the faults of their language. Very close-minded, sometimes scary.
