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.

• Code: waroot/examples/snake/README-en.md

Example: Print Wa

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
2

Example: Print Prime

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 examples/prime

Example: Print Prime with Chinese syntax

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.
