parallel: 一个简单的并行运行Go循环的库

input := []int{1, 2, 3, 4, 5, 6}

parallel.ForEach(input, func(x int) {
  fmt.Printf("Processing %d\n", x)
})

// Output:

// Processing 6
// Processing 3
// Processing 4
// Processing 5
// Processing 1
// Processing 2

input := []int{1, 2, 3, 4, 5, 6}

result := parallel.Map(input, func(x int) int {
  fmt.Printf("Processing %d\n", x)
  return x * 2
})

fmt.Printf("The final result is %v\n", result)

// Output:

// Processing 6
// Processing 1
// Processing 2
// Processing 3
// Processing 4
// Processing 5
// The final result is [2 4 6 8 10 12]
