| Intersperse | 2025-01-16T00:00:00-00:00 |
Intersperse inserts a separator between each element of the slice. Returns an empty slice if the input is empty. Returns the original element if the input has only one element.
package main
import (
"fmt"
u "github.com/rjNemo/underscore"
)
func main() {
nums := []int{1, 2, 3, 4, 5}
fmt.Println(u.Intersperse(nums, 0)) // [1, 0, 2, 0, 3, 0, 4, 0, 5]
// Useful for formatting
words := []string{"apple", "banana", "cherry"}
fmt.Println(u.Intersperse(words, ",")) // ["apple", ",", "banana", ",", "cherry"]
// Single element - no separator added
single := []int{42}
fmt.Println(u.Intersperse(single, 0)) // [42]
}
