Tuples: {number, string}

Arrays: {number}

How does it disambiguate it? Are single-element tuples just never used in practice? To be fair, maybe the only time I've had to use them in TypeScript is via Parameters<T>

In our experience, single-element tuples are just never used in practice. There has been some discussion on how to add syntax for them, but I think it's more of a desire for orthogonality than for a practical need.

Yeah I can't imagine any scenario where it's not just a value or an array of values that happens to have only one value right now.
