How to specify the type for destructuring?

Question

typescript

For example, there is a line:

const [customLayer, map, layer, sidebarContentService] = actions;

How to specify the type for each variable inside []?

For example, I want the compiler to understand that map is a Map type. And that there are methods inside.

I tried like this:

const [customLayer, map<Map> as Map, layer, sidebarContentService] = actions;
