The document then outlines four techniques for refactoring Rails code: 1) intention revealing methods, 2) special case objects, 3) replacing methods with method objects, and 4) service objects. It provides examples and explanations of each technique. Additional resources on service objects are also listed.

- 5. 3 - REPLACE METHOD WITH METHOD OBJECT • 把肥⼤大 method 變成 class • 在 class 內 refactoring
