We can get the length of an array using the .length property like this:
val ourArray = Array(50, 40, 30)
// Printing the length:
println(ourArray.length) // Output: 3
Using the length
We can use the length to access items from the end of an array.
Because arrays are 0-indexed, the index of the last item is length - 1:
val ourArray = Array(50, 40, 30)
// Printing the last item:
println(ourArray(ourArray.length - 1)) // Output: 30
// Printing the second to last item:
println(ourArray(ourArray.length - 2)) // Output: 40
