Arrays vs slices
Translate this TypeScript to idiomatic Go. The collection should
grow with append later — pick the form that lets you do that.

About this theme
Go has fixed-size arrays ([N]T) and dynamically-sized slices ([]T). You almost always want slices. A slice is a view over a backing array — three machine words: pointer, length, capacity. append grows it; make pre-sizes it. The mental model is closer to Rust's Vec than to TS's Array.
