登顶Hacker News！国产编程语言MoonBit（月兔）来了

• 生成与现有解决方案相比显著更小的 WASM 文件

• 更高的运行时性能

• 先进的编译时性能

• 简单但实用的数据导向语言设计

// Moonbit
func fib(num : Int) -> Int {
  fn aux(n, acc1, acc2) {
    match n {
      0 => acc1
      1 => acc2
      _ => aux(n - 1, acc2, acc1 + acc2)
    }
  }

  aux(num, 0, 1)
}

// Go
func fib(n int) int {
  var aux func(n, acc1, acc2 int) int
  aux = func(n, acc1, acc2 int) int {
    switch n {
    case 0:
      return acc1
    case 1:
      return acc2
    default:
      return aux(n-1, acc2, acc1 + acc2)
    }
  }
  return aux(n, 0, 1)
}

// Rust
fn fib(n: i32) -> i32 {
  fn aux(n: i32, acc1: i32, acc2: i32) -> i32 {
    match n {
      0 => acc1,
      1 => acc2,
      _ => aux(n - 1, acc2, acc1 + acc2),
    }
  }
  aux(n, 0, 1)
}
