How to check if an Array is Empty in Go - Step by Step Examples

How to check if an Array is Empty in Go ?

To check if an array is empty in Go, you can use the `len()` function to check the length of the array.

In this example,

We create an array named numbers with some elements.
We use the len() function to check the length of the array.
If the length is greater than 0, the array is not empty; otherwise, it is empty.
Finally, we print whether the array is empty or not.

package main
import "fmt"
func main() {
    numbers := [3]int{1, 2, 3}
    isEmpty := len(numbers) == 0
    fmt.Println("Array is empty:", isEmpty)
}

Array is empty: false

In this example,

We create an array named emptyArray with no elements.
We use the len() function to check the length of the array.
If the length is greater than 0, the array is not empty; otherwise, it is empty.
Finally, we print whether the array is empty or not.

package main
import "fmt"
func main() {
    var emptyArray [0]int
    isEmpty := len(emptyArray) == 0
    fmt.Println("Array is empty:", isEmpty)
}

Array is empty: true
