Quick Answer
Make plugins chainable: always end the plugin function with return this.each(function() { ... }). This returns the original jQuery selection after processing, so users can chain: $(".el").myPlugin().addClass("active"). Never return internal data from the main plugin call - use a separate method or callback for data retrieval.
Answer
Return this at the end of the plugin function. Chain example: $(#el).plugin1().plugin2(). Improves readability and developer experience.
