Let’s understand the string package HasSuffix() method with examples.

strings.HasSuffix() function to check string ends with a suffix

The following go program checks if a string ends with a specified suffix using the strings.HasSuffix() function.

package main

import (
	"fmt"
	"strings"
)

func main() {
	fmt.Println(strings.HasSuffix("GolangSpot", "Spot"))
	fmt.Println(strings.HasSuffix("GolangSpot", "Go"))
	fmt.Println(strings.HasSuffix("GolangSpot", ""))
}

The output of the above program to find string has specified suffix using the HasSuffix() in go is:

true
false
true

In the above program,

The first output has a true value as the given string “GolangSpot” ends with the suffix string “Spot”.

The second output has a false value as the given string “GolangSpot” doesn’t end with the suffix “Go”.

The third output has a true value as the given string “GolangSpot” doesn’t have the suffix “”.
