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:
Example:
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.
For Example
If you want to check if a string starts with a dot
package main
import "strings"
func main() {
str := ".com"
fmt.Println(strings.HasPrefix(str, "."))
}
Terminal:
$ true
