One or more space characters separate a field. The Fields() method in the strings package separates these into an array. It splits into groups of spaces. With Fields() function, we treat many consecutive delimiter characters as one. So several spaces are the same as a single space.
Golang String Fields()
Golang string Fields() is a built-in function that splits a string into substrings removing any space characters, including newlines. The Fields() function accepts a string as an argument and returns an array.
If you want to use Fields() function, then first, you have to import the strings function and then use strings.Fields() function.
Syntax
func Fields(s string) []string
Parameters
The Fields() function takes the string as a parameter, which we need to splits.
Example of Fields() Function
See the following code.
// hello.go
package main
import (
"fmt"
"strings"
)
func main() {
quibi := " TheStranger 50StatesOfFright MostDangerousGame "
series := strings.Fields(quibi)
// Display all fields, first field and count.
fmt.Println(series)
fmt.Println(series[0])
fmt.Println(len(series))
}
Output
go run hello.go [TheStranger 50StatesOfFright MostDangerousGame] TheStranger 3
In the above code, we have defined one string called quibi, which has three fields and spaces.
The strings.Fields() function removes the spaces and converts the string into an array.
Then we have printed the array series, its first element, and the length of the array.
Conclusion
In Golang strings, you are allowed to split a string into a slice using strings.Fields() function.
The Fields() function breaks the string around each instance of consecutive white space characters into an Array.
