strings.EqualFold has no memory overhead and has better performance than strings.ToLower.
This is a performance test:
package bench
import (
"strings"
"testing"
)
func BenchmarkToLower(b *testing.B) {
str1 := "Windows"
str2 := "windows"
for i := 0; i < b.N; i++ {
if strings.ToLower(str1) == strings.ToLower(str2) {
}
}
}
func BenchmarkEqualFold(b *testing.B) {
str1 := "Windows"
str2 := "windows"
for i := 0; i < b.N; i++ {
if strings.EqualFold(str1, str2) {
}
}
}
The result:
goos: darwin
goarch: arm64
BenchmarkToLower-8 31404808 36.99 ns/op 8 B/op 1 allocs/op
BenchmarkEqualFold-8 194780793 5.989 ns/op 0 B/op 0 allocs/op
