Which of the following patterns is NOT facilitated by using closures in JavaScript?

  • Singleton Pattern
  • Module Pattern
  • Factory Pattern
  • Observer Pattern
Closures in JavaScript facilitate patterns like the Singleton Pattern, Module Pattern, and Observer Pattern. These patterns use closures to encapsulate data and create private scopes. However, the Factory Pattern is not primarily facilitated by closures. The Factory Pattern focuses on creating and returning objects or instances, which can be achieved without closures. It relies more on object creation and instantiation rather than scope encapsulation.
