I am facing a situation where I expected TypeScript to give me an error for not specifying types in my constructor, but to my surprise, I did not encounter any errors.
This got me wondering why the error was not being thrown.
This is the code snippet in question:
export interface BaseConfig {
app: express.Application,
routePermission: number,
context: any
}
export class BaseConfig implements BaseConfig {
constructor(
context,
authentication = false,
authenticatedRoute = USER_TYPE.LOGGED_IN_NORMAL_USER
) {
// Initialize Express App
this.routePermission = authenticatedRoute
this.context = context
this.app = express()
Below is my tsconfig:

"compilerOptions": {
"moduleResolution": "node",
