Quick Answer
Handle defaults: $.fn.myPlugin = function(options) { var settings = $.extend({}, $.fn.myPlugin.defaults, options); }; $.fn.myPlugin.defaults = {speed: 400, color: "red"}; Users set global defaults: $.fn.myPlugin.defaults.speed = 600. Per-call options override defaults via $.extend. Always use deep extend ($.extend(true, ...)) for nested option objects.
Answer
Define a defaults object inside the plugin. Merge defaults with user options using $.extend({}, defaults, options). Ensures customization while preserving fallback values.
