I make my [original program][1] more interesting and try to make the builder API more easier to read:
* Now it's a static method of Builder: Pizza.Builder.recipeBuild(...) ,who bake the pizza with customized
* I call it Builder because it has all characters in Builder Pattern:
* Director: recipeBuild
* Builder: Pizza.Builder
* Complex Product: Pizza
Result:
Makeing your pizza by Heart...
