Function Filter

arrayOperations.go:56–66

Filter iterates through an array applying the guard function to each element and returns the elements that pass arr := []int{0,1,2,3,4} func isEven(i int) bool { return i % 2 == 0 } fmt.Println(Filter[int](arr, isEven)) // output: [0,2,4]

(arr []T, guard func(T) bool)

// 	fmt.Println(Filter[int](arr, isEven))
// 	// output: [0,2,4]
func Filter[T any](arr []T, guard func(T) bool) []T {
	var ret []T

	for idx := range arr {
		if guard(arr[idx]) {
			ret = append(ret, arr[idx])
		}
	}

	return ret
}

// Map iterates through an array applying the transform function to each element and returns the modified array
