Subject: refactor: remove unnecessary type casts and improve type safety
X-Git-Tag: ocpp-server@v4.2.0~13
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=ccb61c1cb0155ee414c99ce2648c7dcf661f605e;p=e-mobility-charging-stations-simulator.git

refactor: remove unnecessary type casts and improve type safety

- Remove redundant as any cast in __testable__/index.ts
- Rewrite isEmpty() with native type guards (typeof/instanceof)
- Replace parameter mutation with const in WorkerFactory
- Remove unnecessary cast in MessageChannelUtils
