Coffeescript as a JavaScript low-key little brother is really a good place, use it can improve development efficiency, reduce code errors, the key is to greatly improve the development of pleasure. I feel more and more that I can use the coffee in my project as long as possible.
But perhaps you and I, like me, after understanding the grammar of Coffeescript ready for a try, but faced with how to introduce it into the project and make a worry.

Node.js based on JavaScript, JavaScript is my main development language. Coffeescript is a programming language that is compiled into JavaScript. In fact, Coffeescript language because it can be one-to-one translation of the characteristics of JavaScript, the use of a very flexible. There are a number of ways to bring it into the project, and here I'll do a summary using Coffeescript to write a node.js project.
Run a pure Coffeescript project directly using the

Guests go to the stalls to buy coffee, all the
metadata mode is complex, no schematic code is provided here. By combining the sharing mode with the merging mode, you can ensure that each simple element in the compound element has the same external state, and the inherent state of these simple elements is often different. For more information, see Chapter 31st of Java and mode.

The enjoy meta-mode is also a structured model, which is the last of a description of the structural pattern (because the proxy mode was written earlier). The enjoy meta mode takes a share to avoid the overhead of having the same content object in large numbers. The most common and intuitive kind of overhead is memory loss.Enjoy meta-mode definition
Enjoy meta-mode refers to the use of shared technology to support the reuse of a large number of fine-grained objects. the system uses onl

Design Mode: Template Pattern-conversion, templatepatternTemplate Mode
The template method mode defines the skeleton of an algorithm in a method, and delays some steps to the subclass. The template method allows subclass to redefine some steps in the algorithm without changing the algorithm structure.
Examples of using brewed coffee and brewed tea
Processing Process:
Coffee brewing method: 1. boiling water
! Every time you find a corresponding method, always go up. --The digression!!!!Later, after a panel study, we decided to pull out the basics, such as we made a separate class of coffee, other coffee, such as milk coffee, sweet coffee, and we only packaged the material in a separate class.Improved design:

Author: AxeonCreate a tableFirst, we create one of the tables in our sample database coffees, which contains the necessary information about the coffee sold at the coffee shop, including the name of the coffee, their price, how many pounds they sold this week and the number they have sold so far. About the coffees table we will describe in detail later, as follow
This chapter can be referred to as "giving love a new vision of the people who inherit." This chapter will learn how to use object composition to decorate classes at run time. Once you are familiar with decorating techniques, you will be able to assign new responsibilities to your (or others ') objects without modifying any of the underlying code.
design principles : Classes should be open to extensions and closed to modifications.
Let's start by looking at what the object enhancement means:
In
Decoration mode: as its name implies, it adds layers of coats with him, or adds more adjectives to an object.
Please refer to the demo to show you at a glance.
Package decorator;/*** @ description: decoration mode * @ author Potter * @ date 05:35:07 * @ version V1.0 */public class app {/*** @ Param ARGs */public static void main (string [] ARGs) {coffee = New Tang (New NaI (New Natie (); system. out. println ("coffee's cost =" +
Design Pattern-the decorator pattern)
OK... Let's proceed to the second mode-the decorator Mode
We continue our previous writing habits in the following order ..
1. What is the modifier mode?
Or, according to the definition in the book, the modifier mode-dynamically adds additional responsiveness to an object. The decorator pattern attaches additional reponsibilities to an object dynamically. decorators provide a flexible alternative to subclassing for extending functionality .).
