Follow functional programming principles where possible.
Prefer immutable data (const, readonly).
Support exactOptionalPropertyTypes by explicitly including | undefined in
optional property definitions, e.g. readonly foo?: string | undefined.
Use interfaces for data structures and type definitions.
When a function only takes one parameter and that parameter is an untyped
object, name that parameter's interface Options.
interface Options { /* ... */ }
export default function myFn({ /* ... */ }: Options): void {}
I (e.g., use User instead of IUser)
unless the name is already taken. For example, if a React component is
already named User, then fallback to IUser for the interface.
