What Are Patterns?

This video tutorial introduces various design patterns in JavaScript, explaining their use in software design. It covers patterns like module, singleton, factory, observer, mediator, and state, highlighting their applications in structuring code and managing object creation. The tutorial also includes a project demonstration using these patterns to build a website with dynamic content changes.
