+## Arrays
+
+Arrays in Mana are ordered collections of values. Arrays are created using square brackets. Arrays can contain values of any type, including other arrays. Arrays are indexed using square brackets. The index is an integer value that represents the position of the element in the array. Arrays are zero-indexed, which means that the first element in the array is at index 0.
+
+```rust
+let numbers = [1, 2, 3, 4, 5];
+
+let first = numbers[0]; // first = 1
+
+let last = numbers[len(numbers) - 1]; // last = 5
+```
+
+```rust
+let mixed = [1, "two", true, fn(x) { x * x; }];
+let c = 69;
+
+let f = mixed[3](5); // f = 25
+
+let u = ["one", "two", 3][5 - 4]; // s = "two"
+
+let k = mixed[c - 67]; // k = true
+```
