Any

Any returns true if any of the values in the slice pass the predicate truth test. Short-circuits and stops traversing the slice if a true element is found.

package main

import (
	"fmt"
	u "github.com/rjNemo/underscore"
)

func main() {
	nums := []int{1, 2, 4, 6, 8}
	isEven := func(n int) bool { return n%2 == 0 }
	fmt.Println(u.Any(nums, isEven)) // true
}
