What is the EqualFold function in Golang?
The EqualFold() function in Golang is an inbuilt function of strings package which is used to check whether the given strings (UTF-8 strings) are equal. The comparison is not case-sensitive. It accepts two string parameters and returns True if both the strings are equal under Unicode case-folding (i.e., case-insensitive), False otherwise.
Syntax
func EqualFold(s, t string) bool
Where s and t are strings. It returns a Boolean value.
Example
The following example demonstrates how to use EqualFold() in a Go program −
package main
import (
"fmt"
"strings"
)
func main() {
// Intializing the Strings
R := "Welcome to Tutorialspoint"
S := "WELCOME TO TUTORIALSPOINT"
fmt.Println("First string:", R)
fmt.Println("Second string:", S)
// using the EqualFold function
if strings.EqualFold(R, S) == true {
fmt.Println("Both the strings are equal")
} else {
fmt.Println("The strings are not equal.")
}
}Output
It will generate the following output −
First string: Welcome to Tutorialspoint Second string: WELCOME TO TUTORIALSPOINT Both the strings are equal
Observe that the comparison is not case-sensitive.
Example
Let us take another example −
package main
import (
"fmt"
"strings"
)
func main() {
// Initializing the Strings
x := "Prakash"
y := "PRAKASH"
z := "Vijay"
w := "Pruthvi"
// Display the Strings
fmt.Println("First string:", x)
fmt.Println("Second string:", y)
fmt.Println("Third string:", z)
fmt.Println("Fourth string:", w)
// Using the EqualFold Function
test1 := strings.EqualFold(x, y)
test2 := strings.EqualFold(z, w)
// Display the EqualFold Output
fmt.Println("First Two Strings are Equal? :", test1)
fmt.Println("Last Two Strings are Equal? :", test2)
}Output
It will produce the following output −
First string: Prakash Second string: PRAKASH Third string: Vijay Fourth string: Pruthvi First Two Strings are Equal? : true Last Two Strings are Equal? : false
