-// Advanced Arrays Demo
-
-// Start with a basic array
-arr = [1, 2, 3]
-print(arr)                       // -> [1, 2, 3]
-
-// length (also works on strings)
-print(len(arr))                  // -> 3
-print(len("hello"))              // -> 5
-
-// push returns new length and mutates the array
-print(push(arr, 99))             // -> 4
-print(arr)                       // -> [1, 2, 3, 99]
-
-// pop returns the removed element and mutates the array
-last = pop(arr)
-print(last)                      // -> 99
-print(arr)                       // -> [1, 2, 3]
-
-// set(array, index, value) sets in place and returns the value
-print(set(arr, 1, 42))           // -> 42
-print(arr)                       // -> [1, 42, 3]
-
-// insert(array, index, value) inserts before index; returns new length
-print(insert(arr, 1, 7))         // -> 4
-print(arr)                       // -> [1, 7, 42, 3]
-
-// remove(array, index) removes at index and returns the element
-removed = remove(arr, 2)
-print(removed)                   // -> 42
-print(arr)                       // -> [1, 7, 3]
-
-// slicing: a[i:j] (end is exclusive), a[i:-1] means to the end
-s1 = arr[1:3]
-print(s1)                        // -> [7, 3]
-s2 = arr[0:-1]
-print(s2)                        // -> [1, 7, 3]
-
-// concatenation with +
-tail = [10, 20]
-combined = arr + tail
-print(combined)                  // -> [1, 7, 3, 10, 20]
