Report #98740

[bug\_fix] Parameter 'event' implicitly has an 'any' type. \(TS7006\)

Add an explicit type annotation to the parameter, e.g. document.addEventListener\('click', \(event: MouseEvent\) => \{ ... \}\). Alternatively, let TypeScript infer the type from a typed wrapper, but do not disable noImplicitAny unless you are temporarily migrating legacy code.

Journey Context:
You add an event listener in a TypeScript file: document.addEventListener\('click', event => \{ ... \}\). With noImplicitAny enabled through strict: true, tsc reports TS7006 because the callback parameter has no annotation and the compiler cannot infer a useful type from the outer call. The compiler would normally fall back to any, and noImplicitAny forbids that fallback. Annotating event as MouseEvent restores IntelliSense and catches mistakes like event.targett. This is the intended behavior: implicit any silently disables type-checking for that value.
