Nodejs becomes a norm--advice

Nodejs does not have an official document that specifies the code style of the application, but has some de facto conventions.

1. Indent- Two spaces

2. Line width-80 characters

3. Statement delimiter

   It is recommended to use semicolons, even if there is only one statement on a line, do not omit semicolons
   

4. Variable definition-- always use var to define variables and ensure that each statement defines a variable

5. Variable name and attribute name--Small hump-type naming method

6. Function--General function small hump type; construction function Big Hump

7. Quotation marks--unity as single quotation mark

8. Initialization of associative arrays

   var = {Put in a row, below a pair of key values for each line, keep two spaces indented, end with a semicolon,}; Finally a separate line;

   For each pair of key values, the quotation marks are not used unless there are spaces or illegal characters in the key value name.

9. Equal sign--= = =

10. Named functions

    The constructor and callback function are named as much as possible, and the call stack can be clearly displayed when debugging.

    A callback function that contracts the first argument is the Error object err.

11. Object definition-Try to define all member functions through the prototype, define the attributes within the constructor, and then create the object with the new keyword on the constructor; never define the property as a prototype.

12. Inheritance-Use the Inherits function in the Util module as much as possible.
