In other programming +languages, they'd simply be called Arrays, but since Rust operates on a +bit of a lower level, an array in Rust is stored on the stack (meaning it +can't grow or shrink, and the size needs to be known at compile time), +and a Vector is stored in the heap (where these restrictions do not apply). + +Vectors are a bit of a later chapter in the book, but we think that they're +useful enough to talk about them a bit earlier.
