V is easier than C and fast like C.
Specs
Question Ranking
Pros
Pro Rich GTK Support
Vala developed by Gnome Foundation.
Pro Fast
Underneath there is C. It makes some stuff easier to write than it would be with plain C code.
Pro Easy Syntax
Vala is syntactically similar to C# and includes several features such as: anonymous functions, signals, properties, generics, assisted memory management, exception handling, type inference, and foreach statements
Pro C compatible API (and ABI)
C programs can use libraries written in Vala, and vice versa.
Pro Good documentation
There is Valadoc and most of the libraries have Devhelp packages.
Pro Well-integrated with C language
Vala itself is compiled to C, therefore it can use the vast ecosystem of C language, with least effort.
Pro Stable ABI
You can write a library with ABI stability.
Pro A general purpose language
Vala is compiled to C and only requires GLib - or even nothing (posix profile)
Pro Fast like C
V is easier than C and fast like C.
Pro C Interop
Can import C libraries, structs, and headers.
Pro Cross-platform
Compile to many OSes.
Pro Simplicity
V is simple and powerful.
Pro Can create multi-OS GUIs
Multi-OS GUI creation is more integrated into the language than others.
Pro Clear syntax
Highly understandable language.
Pro Sum types
V has Sum Types.
Pro Generics
V has generics.
Pro Closures
V has closures, which gives the user additional options and usefulness.
Pro Safety
V is very safe.
Pro Single paradigm
Follows the philosophy that there should be only one way to do something, as opposed to multi-paradigm languages like C++.
Pro Supports concurrency and channels
Can run functions concurrently that communicate over channels.
Pro Fast compile times
Compiles programs fast, less waiting around, so more productive and fun.
Pro Friendly and helpful community
Just check the V Discord channel or their GitHub Discussions and you will see by yourself.
Pro Inline assembly
Can add Assembly code.
Cons
Con Very few resources allocated to the language
Only a single person is working on Vala full time. Gnome Foundation isn't allocating sufficient resources to properly maintain Vala.
Con A very naïve approach to the real problem
Vala just adds more complexity to the game. No real benefits in using a 'programming language emulator' for UI code, you may think it adds to productivity but it's just a way to make the problem last longer, reinventing the wheel everytime and worse.
Con Very limited adoption
Vala isn't used in areas other than GTK development, and no major business has adopted the language.
Con Not a general purpose language
Can't use Vala in multiple software development areas.
Con Very limited tooling
Though using Gnome Builder, you can debug it easily.
Con Heavy reliance on GObject
Heavy reliance on GObject types, although Vala can be used without GObject. (posix profile)
Con Not well documented
It already has tons of documentation, even a book about Vala.https://leanpub.com/vala https://wiki.gnome.org/Projects/Vala/Documentation
Con No stable version
No stable version of Vala released for over a decade so far. Means that Vala isn't production ready.
Con Rapid changes in a language syntax/features
Since V language under a continuous development and core syntax and features will be "frozen" in a version 1.0.0, updating from older version of a language can cause a code rewrite of previously working program.
Con V 1.0 release was planned for December 2019
The first version of the language was publicly released in June of 2019, version 0.1.x. First beta version of the language was released June of 2022, version 0.3. x. Language has progressed faster than most. Welcomes contributors to join the project.
