Sorting Slices

sort.Slice and helpers.

Why Sorting Matters

Sorting puts elements in a defined order. Go's sort package from the standard library handles this efficiently.

You rarely write your own sort algorithm in Go. Instead you call helpers that work on slices.

To use the package, import it with import "sort". It lives in the standard library, so no external download is needed.

package main

import (
	"fmt"
	"sort"
)

func main() {
	fmt.Println("sort imported")
	_ = sort.IntsAreSorted([]int{1, 2, 3})
}
