Build will fail; resolve before shipping.
A strict mode error (TS7033): Property 'X' implicitly has type 'any', because its get accessor lacks a return type annotation.. This diagnostic is emitted by the TypeScript compiler when property 'X' implicitly has type 'any', because its get accessor lacks a return type annotation..
- 1TypeScript cannot infer the type and defaults to 'any' with --noImplicitAny
- 2Missing type annotation or type parameter
TypeScript compiler reports TS7033 during type checking.
// Triggers TS7033 // Property 'X' implicitly has type 'any', because its get accessor lacks a return type annotation.
expected output
error TS7033: Property 'X' implicitly has type 'any', because its get accessor lacks a return type annotation.
Fix
Add an explicit type annotation
WHEN When TypeScript cannot infer the type
// Before (implicit any)
function process(value) { return value; }
// After (explicit type)
function process(value: string): string { return value; }Why this works
Adding explicit type annotations removes the implicit 'any' and enables full type checking.
✕ Suppress with @ts-ignore instead of fixing the type
ts-ignore hides real type errors and makes refactoring unsafe.
