Wa (Chinese name "凹", which pronounced "Wa") is a general-purpose programming language designed for for WebAssembly. The goal is to provide a simple, reliable, easy-to-use, statically typed language for high-performance web applications. The code generator and runtime are fully independently developed (not dependent on external projects such as LLVM). Currently, Wa is in the engineering trial stage.

Print rune and call function：

import "fmt"global year: i32 = 2023func main {println("hello, Wa!")println(add(40, 2), year)fmt.Println(1+1)}func add(a: i32, b: i32) => i32 {return a+b}

Execute the program:

$ wa run hello.wa hello, Wa!42 20232

Print prime numbers up to 30:

func main {for n := 2; n <= 30; n = n + 1 {isPrime: int = 1for i := 2; i*i <= n; i = i + 1 {if x := n % i; x == 0 {isPrime = 0}}if isPrime != 0 {println(n)}}}

Execute the program:

$ cd waroot && wa run -target=wasi examples/prime2357111317192329

Print prime numbers up to 30:

引于 "书"【启】：  // 输出30以内的素数  从n=2，到n>30，有n++：    设素=1    从i=2，到i*i>n，有i++：      设x=n%i      若x==0则：        素=0      。    。    若素!=0则：      书·曰：n    。  。。

Output is the same as the previous example.

Chrome builtin Gemini Nano Demo:

import "ai"func main {ai.RequestSession(func(session: ai.Session){session.PromptAsync("Who are you?", func(res: string) {println(res)})})}
