Fields()

The Fields() function in Go is used to split a string into substrings based on whitespace and return a slice of the substrings. It removes any leading or trailing whitespace and treats consecutive whitespace characters as a single separator.

Syntax

strings.Fields(str)

Where str is the original string.

Example

The following example demonstrates the use of the strings.Fields() function.

package main
import (
 "fmt"
 "strings"
)

func main() {
  str := "Hello World Golang"
  fields := strings.Fields(str)

  fmt.Println(fields)
}

The output will be:

[Hello World Golang]
