Instead of,❌ioutil.ReadFile use ✔ os.ReadFile
https://pkg.go.dev/io/ioutil#ReadFile


ioutil.ReadFile is deprecated: As of Go 1.16, this function simply calls [os.ReadFile].

Deprecated code:
file_data, err := ioutil.ReadFile("./index.html")
if err != nil {
	fmt.Println(err)
}
fmt.Println(file_data)

Corrected code:
file_data, err := os.ReadFile("./index.html")
if err != nil {
	fmt.Println(err)
}
fmt.Println(file_data)
