Putting the interface into a module isn't totally necessary but it provides a couple small benefits including: the "publicly" widely-used type-annotation that is used throughout implementation code becomes slightly smaller since it no longer includes the keyword typeof, unlike the wrapped ambient class/interface declaration, the exported/outward-facing identifier is strictly a type (alias), so an error will now occur if anyone tries to instantiate it or use it in an extends clause (or use it anywhere else a runtime value is expected). The value of readonly field can be changed. JEEP Wrangler Unlimited 2.8 CRD DPF Rubicon Auto [rif.
