When comparing Julia vs Zig, the Slant community recommends Julia 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?” Julia is ranked 14th while Zig is ranked 40th. The most important reason people chose Julia is:
Julia runs almost as fast as (and in fact in some cases faster than) C code.

Pros
Pro Almost as fast as C
Julia runs almost as fast as (and in fact in some cases faster than) C code.
Pro Nice regular syntax
Julia code is easy to read and avoid a lot of unnecessary special symbols and fluff. It uses newline to end statements and "end" to end blocks so there is no need for lots of semicolons and curly braces. It is regular in that unless it is a variable assignment, function name always comes first. No need to be confused about whether something is a method on an object or a free function.
Unlike Python and Ruby, since you can annotate the types a function operates on, you can overload function names, so that you can use the same function name for many data types. So you can keep simple descriptive function names and not have to invent artificial function names to separate them from the type they operate on.
Pro REPL-based
The Julia REPL allows quickly testing how some code behaves and gives access to documentation and package management immediately in the REPL.
Pro Strong dynamic typing
Dynamic and high level, but does not isolate the user from properly thinking about types. Can do explicit type signatures which is great for teaching structured thinking.
Pro Great standard REPL
Out of the box Julia has a very good Read-Eval-Print-Loop, which both completes functions and types, as well as completion based on history of previous statements. It integrates well with the shell and has an excellent online help system.
Pro Written in itself
The Julia language is written in itself to a much larger extent than most other languages, so a budding programmer can read through the depths of the standard library and learn exactly how things work all the way down to the low-level bit-twiddling details, which can be englightening.
Pro Amazing learning curve
Julia requires no boilerplate code – a beginner needs to write only the parts they care about. This combined with the REPL provides the best learning experience available.
Pro High-level code
Julia provides a high level of abstraction, making platform-independent programming trivial and easing the learning curve.
Pro Function overloading
You can have multiple functions with the same name, but doing different things depending on function arguments and argument types.
Pro Strong Metaprogramming
Julia allows you to edit Julia code in the language itself and write powerful macros. It is a great introduction to metaprogramming features
Pro Powerful n-dimensional arrays
Julia has built in n-dimensional arrays similar in functionality as Python's numpy.
Pro Function and operator broadcasting
You can perform operations on scalars, for example 2^2 or [1, 2, 3].^2.
Pro Some safety
It's safer than C, at least.
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 Compile-time execution
Zig can execute code at compile-time, allowing for more performant and readable programs.
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 C Interop
Zig programs can import C libraries and export header files to be used in C 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.
Cons
Con Young language with limited support
Julia was released in 2012. Due to its short existence, there is a limited amount of support for the language. Very few libraries exist as of yet, and the community is still quite small (though growing quickly).
Con 1-based array and column major
This design probably comes from Matlab, but makes it unnatural to interface C and C++ and python.
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 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 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 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.
