Wa is a general-purpose programming language designed for developing robustness and maintainability WebAssembly software. Instead of requiring complex toolchains to set up, you can simply go install it - or run it in a browser.

Print rune and call function：
import "fmt"
global year: i32 = 2023
func 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 2023

Print prime numbers up to 30:
func main {
for n := 2; n <= 30; n = n + 1 {
isPrime: int = 1
for 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/prime

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.
