+The primary benefit of TypeScript is type-safety, and attempting to escape from the type-safety should be a conscientious decision by the developer. So ensure that noImplicitAny is true, and keep your code type-aware and able to be refactored. Enabling "noImplicitAny" doesn't mean your project will never use the "any" type.
