TypeScript
Parameter implicitly has an any type
Parameter '{0}' implicitly has an 'any' type.TypeScript could not infer a safe type for a parameter and, with noImplicitAny enabled, reported it as an error.
Error AtlasError Documentation and ResolutionObserved message
Parameter '{0}' implicitly has an 'any' type.Why it happens
- A function parameter has no type annotation and TypeScript cannot infer a specific type.
- The project enables noImplicitAny, which turns implicit any cases into errors.
- A callback or helper function is declared without enough contextual typing.
How to fix it
- Add an explicit type annotation to the parameter.
- Refactor the function so TypeScript can infer the parameter type from context.
- Review noImplicitAny settings only if the project intentionally allows untyped parameters.
