## Use `type` rather than `interface` for named parameters and POJO return values.
`type` and `interface` can be used somewhat interchangebly used, but let's use `type` to describe data and `interface` to describe (polymorphic) behaviour.
`type` and `interface` can be used somewhat interchangeably, but let's use `type` to describe data and `interface` to describe (polymorphic) behaviour.
Good examples of data are option objects to have named parameters, and POJO (plain old javascript objects) without any methods, just fields.

## Use `Record<string, any>` to describe a type that accepts any Javascript object.
Prefer this over index signature, `any` or `object`.
