[[Rust]]
[[Variables lives on the stack]]
[[When heap data is deallocated]]
[[Ownership]]
---
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.
