Replicate creates a slice containing count copies of value. Returns an empty slice if count is less than or equal to 0. Useful for initialization and testing.
package main
import (
"fmt"
u "github.com/rjNemo/underscore"
)
func main() {
// Basic usage
fmt.Println(u.Replicate(3, "hello"))
// ["hello", "hello", "hello"]
// Numbers
fmt.Println(u.Replicate(5, 0))
// [0, 0, 0, 0, 0]
// Zero count
fmt.Println(u.Replicate(0, 42))
// []
// Negative count
fmt.Println(u.Replicate(-5, "x"))
// []
// Use case: initialize with default values
defaultScores := u.Replicate(10, 100)
fmt.Println(defaultScores)
// [100, 100, 100, 100, 100, 100, 100, 100, 100, 100]
// Use case: creating separators
separator := u.Replicate(40, "-")
fmt.Println(u.Reduce(separator, func(s, acc string) string { return acc + s }, ""))
