How to Check if String starts with Specific Prefix in Go ?

Answer

In Go, you can use the 'strings.HasPrefix' function to check if a string starts with a specific prefix.

✐ Examples

1 Check if String contains specific Prefix using 'strings.HasPrefix' function

In this example,

We import the 'strings' package to access the 'HasPrefix' function.
We create a function 'startsWithPrefix' that takes a string and a prefix as input.
We use the 'strings.HasPrefix' function to check if the string starts with the specified prefix.
If the string starts with the prefix, 'true' is returned; otherwise, 'false'.
Finally, we print the result.

Go Program

package main

import (
    "fmt"
    "strings"
)

func startsWithPrefix(str, prefix string) bool {
    return strings.HasPrefix(str, prefix)
}

func main() {
    str := "Hello World"
    prefix := "Hello"
    startsWith := startsWithPrefix(str, prefix)
    fmt.Println("String starts with prefix '", prefix, "': ", startsWith)
}

Output

String starts with prefix ' Hello ':  true
