Quick Answer
Reusable plugin: use $.fn.myPlugin pattern, support init/method calls ($.fn.myPlugin = function(action, opts) { if (action === "destroy") cleanup(); else init(opts); }), store state in .data(), return this for chaining, namespace events for clean removal. Follow jQuery plugin boilerplate as a starting template.
Answer
Extend $.fn with a custom function. Accept options for flexibility. Return this for chainability. Allows multiple elements to share the same behavior. Promotes modular and maintainable development.
