What is strings.TrimSpace() Function in Golang

by

In Go, strings.TrimSpace() is a built-in function that removes all leading and trailing white space (spaces, tabs, newlines, etc.) from a string.

Syntax

func TrimSpace(str string) string

Parameters

The str is the string to be trimmed.

Return value

The strings.TrimSpace() function returns the trimmed string.

Example

package main

import (
  "fmt"
  "strings"
)

func main() {
  str := "   This is a string with leading and trailing spaces.   "
  fmt.Println("Before:", str)
  fmt.Println("After:", strings.TrimSpace(str))
}

Output

Before:   This is a string with leading and trailing spaces.

After: This is a string with leading and trailing spaces.

In this example, strings.TrimSpace() removes the leading and trailing spaces from the string variable str. The output string is then printed to the console.

The strings.TrimSpace() function only removes leading and trailing spaces. If you want to remove spaces from within the string, you can use the strings.ReplaceAll() function to replace spaces with an empty string.
