Go StartsWith(str string)


Is there a StartsWith(str1, str2 string) function that can check if str1 is a prefix of str2 in Go language?

I want a function similar to the Java’s startsWith().


The strings package has what you are looking for. Specifically the HasPrefix function: http://golang.org/pkg/strings/#HasPrefix


fmt.Println(strings.HasPrefix("my string", "prefix"))  // false
fmt.Println(strings.HasPrefix("my string", "my"))      // true

That package is full of a lot of different string helper functions you should check out.
