What are @tsconfig/strictest's main functionalities?

Strict Type-Checking

Enables all strict type-checking options in TypeScript, ensuring that the code adheres to the highest standards of type safety.

{"compilerOptions":{"strict":true,"noImplicitAny":true,"strictNullChecks":true,"strictFunctionTypes":true,"strictBindCallApply":true,"strictPropertyInitialization":true,"noImplicitThis":true,"alwaysStrict":true}}

No Implicit Returns

Ensures that all functions have explicit return statements, preventing accidental undefined returns.

{"compilerOptions":{"noImplicitReturns":true}}

No Fallthrough Cases in Switch

Prevents fallthrough cases in switch statements, which can lead to unexpected behavior.
