 Once you've learned about optional parameters and function type expressions, it's very easy to make the following mistakes when writing functions that invoke callbacks:
 
 ```ts twoslash
-function myForEach(arr: any[], callback: (arg: any, index?: number) => void) {
+function myForEach<T>(arr: T[], callback: (arg: T, index?: number) => void) {
