+---
+
+The heap is where data can live indefinitely and we can create pointers to it on the stack using a Box.
+
+```rust
+let a = Box::new([0; 1_000_000]);
+let b = a;
+```
+
+Creates an array with 1 million entries on the heap and two variables on the stack that are a *pointer* to that heap data.
