Quick Answer
Create a jQuery plugin: $.fn.myPlugin = function(options) { var settings = $.extend({color: 'red'}, options); return this.each(function() { $(this).css('color', settings.color); }); }; Wrap in (function($) {})(jQuery) IIFE for $ safety. Return this.each() to maintain chainability. Use $.extend for default options merging.
Answer
Plugins extend jQuery functionality. Pattern: extend $.fn with a function. Accept options and maintain chainability. Ensures modular, reusable, configurable functionality.
