V

About V

V is a simple language for building maintainable programs. The syntax is similar to Go, with performance as fast as C.

V is still in beta development, but already very powerful.

With many built-in safety features, V helps your code run no matter what you throw at it: bounds checking, no undefined values, immutable variables by default, Option/Result types and mandatory error checks, and no null.

V is written in V and compiles itself in under a second, and can call C code with no costs. It also has built-in formatting, code profiling, testing, and docs generation.

The official website is vlang.io and the docs are all in this markdown file.

Key Features of V

Concurrency

V can run concurrently using `spawn` to start a new thread

Cross Platform

V is cross-compiled with v -os windows or v -os linux

Documentation

V includes vdoc to get instant documentation generated from the module's source code

Fast

V is written in V and compiles itself in under a second

Safe

No null, no undefined values, no undefined behavior, immutable by default

Tiny

V has a space requirement to compile of <10MB, Rust is 30 GB and Go is 525 MB
