 1. `obj?.prop` -- returns `obj.prop` if `obj` exists, otherwise `undefined`.
 2. `obj?.[prop]` -- returns `obj[prop]` if `obj` exists, otherwise `undefined`.
-3. `obj?.method()` -- calls `obj.method()` if `obj` exists, otherwise returns `undefined`.
+3. `obj.method?.()` -- calls `obj.method()` if `obj.method` exists, otherwise returns `undefined`.
 
 As we can see, all of them are straightforward and simple to use. The `?.` checks the left part for `null/undefined` and allows the evaluation to proceed if it's not so.
