有没有一种方法可以编写用于在TypeScript中解构对象数组的类型？

Question

I need to write typings for a structure like this one:

const [{ start }] = myObjectsArray;

However I cannot write it as just a string, or an object like this one:

const [{ start }]: { start: string } = myObjectsArray;

Because in TypeScript I get an error, saying that it is no an array type. When I try to type something like

const [{ start }]: [{ start: string }] = myObjectsArray;

I get an error, that the structure is missing the property '0'.

What is the way to correctly write types for a structure like this one?

It looks like I'd found the answer while I was writing the question, so I'm posting it here.

The way that turns out to be working in such cases is the next one:

const [{ start }]: Array<{ start: string }> = myObjectsArray;
