TypeScript parameter implicitly has an any type
error TS7006: Parameter 'X' implicitly has an 'any' type.
TypeScript reported a function parameter with no explicit type and no safe inference under noImplicitAny rules.
Error AtlasError Documentation and ResolutionObserved message
error TS7006: Parameter 'X' implicitly has an 'any' type.
Why it happens
- A function parameter has no declared type and TypeScript cannot infer one safely.
- The project enables noImplicitAny, so silent any inference is treated as an error.
- A callback or utility function lost contextual typing during refactoring.
How to fix it
- Add an explicit type annotation to the parameter.
- Refactor the function so TypeScript can infer the parameter type from surrounding context.
- Only relax noImplicitAny if that tradeoff is intentional for the whole project.
