A type-checking error (TS2602): JSX element implicitly has type 'any' because the global type 'JSX.Element' does not exist.. This diagnostic is emitted by the TypeScript compiler when jSX element implicitly has type 'any' because the global type 'JSX.Element' does not exist..
- 1TypeScript cannot infer the type and defaults to 'any' with --noImplicitAny
- 2Missing type annotation or type parameter
TypeScript compiler reports TS2602 during type checking.
// Triggers TS2602 // JSX element implicitly has type 'any' because the global type 'JSX.Element' does not exist.
expected output
error TS2602: JSX element implicitly has type 'any' because the global type 'JSX.Element' does not exist.
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.
