Trim() FUNCTION

Trim() Function

The Trim() Function is used to remove any unwanted character from the String.

Example :

package main
import "fmt"
import "strings"
    
func main() {
    
    x := "   Hello  "
    y := strings.Trim(x," ")
            
    fmt.Println(y)     	 	
}

Output :

Hello

In the above code, we have declared a String ' Hello ' with leading and trailing spaces.

x := " Hello "

Then we have used the 'Trim()' function to remove any unwanted spaces from beginning and end.

y := strings.Trim(x," ")

Unwanted spaces are stripped out of it.

Now, let us say you want have asterisk '*' in front of the String and after the String. And you want to remove them.

Example :

package main
import "fmt"
import "strings"
    
func main() {
    
    x := "***Hello**"
    y := strings.Trim(x,"*")
            
    fmt.Println(y)     	 	
}

Output :

Hello

In the above code, we have declared a String ' Hello ' with leading and trailing asterisk '*'.

x := "***Hello**"

Then we have used the 'Trim()' function to remove any asterisk '*' from beginning and end.

y := strings.Trim(x,"*")

And asterisk '*' are stripped out of it.
