Strict

⬅️ FEM TypeScript Fundamentals

Strict

• noImplicitAny: forces us to provide explicit types for every function parameter

• strictNullChecks: TypeScript doesn’t allow us to assign null or undefined to variables unless their types include null or undefined

• strictPropertyInitialization

• strictFunctionTypes

• Strict mode is disabled by default, always set:

{"compilerOptions": {"strict": true}}
