-declare function render(x: unknown);

-In an object destructuring pattern, `shape: Shape` means "grab the property `shape` and redefine it locally as a variable named `Shape`.
-Likewise `xPos: number` creates a variable named `number` whose value is based on the parameter's `xPos`.
-
-Using [mapping modifiers](/docs/handbook/2/mapped-types.html#mapping-modifiers), you can remove `optional` attributes.
