Golang : How to check if a string starts or ends with certain characters or words?
Problem :
You are building a rule for parsing text strings and you want to determine if a string starts or ends with certain words or characters. How to do that?
Solution :
Use strings.HasPrefix()
function to check if a string starts with certain word.
For example,
if strings.HasPrefix(input, "please") {
return "You don't have to be so polite"
}
to check if the strings ends with certain character or word. Use strings.HasSuffix()
function.
