Go: Equals ignore case

Comparing 2 strings ignoring case can be achieved using 2 approaches:

• make it lower/upper case than compare it
• using strings.EqualFold

sample benchmark code for both approaches

package main

import (
	"strings"
	"testing"
)

func getData() (x string, y string) {
	x = "ASDasd"
	y = "asdASD"
	return
}

func Benchmark_toLower(b *testing.B) {
	x, y := getData()
	for i := 0; i < b.N; i++ {
		if strings.ToLower(x) == strings.ToLower(y) {
		}
	}
}

func Benchmark_EqualFold(b *testing.B) {
	x, y := getData()
	for i := 0; i < b.N; i++ {
		if strings.EqualFold(x, y) {
		}
	}
}

Here the benchmark result:
