Recently work relaxed point, think of the previous always see a word promise, so patience to learn a bit. One: What is promise? Why would there be such a thing? First, the promise is created to address the way JavaScript writes code in asynchronous programming.With the development of JavaScript, there are more and more asynchronous scenes. The front end has ajax,settimeout, and the backend node is more asynchronous. In traditional practice, it is the various callback nesting callbacks. Code ca

Personal integration of some common development norms, for reference only. The source code file encoding should be UTF-8. Any character that needs to escape the string representation (such as \b, \ t, \ n, \f, \ r, \, \ etc) is represented by this escape string. The top portion of the entire source file should have the following four pieces, separated by a blank line between each section . 1.License or Copyright declaration information . 2. Package declaration statement, and package declaration

default is to synchronize the name and code, the previous check box to remove the line. PowerDesigner Design Database Specification ----First draft by Rojun Demand: Although our database design model can meet the development requirements, but also save the development time, but this design will be the maintenance of the project after the revision of the cost of the increase. The database table field will affect the main program on the modificatio

Today describes how to use modules in a standardized manner. (up to the above) Specification of Modules First think about why the module is important? Because of the module, we can more easily use other people's code, want what function, loaded what module. However, this has a prerequisite, that is, we must write the same way the module, otherwise you have your writing, I have my writing, it is not a mess of the set! This is even more important

Code | Specification 1 Introduction (Introduction) 1.1 Why should there be coding specifications Coding specifications are particularly important for programmers for a number of reasons: -80% of the cost of a software lifecycle is to maintain -Almost no software, throughout its lifecycle, is maintained by the original developer -Coding specifications can improve the readability of the software, allowing programmers to understand the new code as quick

Unified Universal naming in the team, the general naming needs to accumulate slowly, this cumulative result I call it code specification, code specification can lead the Ascension Program Ape's coding ability.The areas that are oriented in different teams are very distinct, but the same domain should be named as a professional domain. It also needs to accumulate slowly, and it also belongs to the code

Last week, a day's time to write a log slice, everyone is very supportive of cooperation, the internal modules are used together. Technically it is a aspectj, there is no difficulty. The key is to make a lot of modules to use together, to form a specification. The norm is a magical thing. For example, the Internet itself is a set of norms. The so-called bandwidth is what we have to comply with the voltage requirements. such as the magic of HTTP, which

Code Coding Specification Objective: To be able to standardize in the coding process, to develop good behavior habits for future program development.Code Coding specifications Use Scope: Java project development. Package naming specification:Objective: The nomenclature of package should reflect the good division of Project resources. The Servlet class contains the package naming specification: Company nam

result that matches that condition.First look at the implementation of the filter. In the Get action method of countries, I use the Countryresourceparameters class as a parameter, so to increase the filter for a property, just extend the class, The added attribute name is the same as the property name inside the Resourcemodel:Then there is the way to modify the countryrepository inside:The first step is to append the filter before performing the paging action, which must be iqueryableBecause of

some naming conventions or JS book naming conventions, like to mix naming conventions with syntax such as:1. Use "Var" to define, initialize variables to prevent global variables, a multi-variable definition using "," (itself this way is very controversial).2. The end must be added ";" Prevent JS execution effect is not the same as imagined.3. Judge two number equal use "= = =" Do not use "= =". (In fact, the "=" problem rarely occurs, and JS's syntax section will also refer to the proposed use

The Python enhancement suggestion, also known as PEP8, is a style guideline for formatting Python code. As long as you have the syntax, you can write Python code whatever you want. However, a consistent style makes your code more affinity and understandable, and facilitates collaboration when shared with other Python programmers in a large community. But even if you only read your code yourself, following this style specification will make it easier t

true for documented development methods. Or the words, should be changed. If your system is simple and unlikely to expand in the future, this design is simple and efficient. But if you are designing a medium and large system, the following questions will confuse you: Is this design easy to expand? Future need to add new query logic, resulting in a lot of related code to be modified, how to do? Over time, this interface will become larger and bigger, and you'll be a hammer in the team. I modi

Checkstyle is a project under SourceForge that provides a tool to help Java developers comply with certain coding specifications. It automates the process of code specification checking, freeing developers from this important but tedious task. It can check the code according to the set coding rules. For example, the specification of variable name, method body maximum number of lines, duplicate code check an

This specification is designed for JavaScript functional programming styles and the fact that the company relies heavily on jquery for coding.Eval,with and caller (use strict requirements for ecma262 V5) are prohibited. Eval only allows machine generation at encryption time.The declaration variable must be prefixed with the VAR keyword, except in the for (;;) A continuous declaration is not allowed in principle in statements such as loops. Because the

Specification descriptionThis is the code writing specification that the front-end development team follows and conventions, and is intended to improve the normative and maintainability of the code.Basic guidelinesConform to Web standards, semantic HTML, structural performance behavior separation, good compatibility. Page performance, code requirements concise and clear order, as far as possible to reduce t

Code Authoring Specification Comments and update notes You have to annotate your code, even if no one else touches it like you. Usually, when you delve into a problem, you'll know exactly what the code is for, but when you come back in a week, you're going to have to drain a lot of brain cells to figure out how it works.Annotations cannot go to extremes: each individual variable or a single row. However, you should usually record all fun

information for designated hotels/// string languagecode) ;The summary,param,returns tag embedded here is only part of the markup that Visual Studio recognizes, but in IntelliSense, it does not list all the tags in the C # specification, and the missing parts can only be inserted manually. These manual tags are very useful, and if they are set appropriately, it will be helpful to export them as external documentation.Three. Generate an XML fil

Java Development Specification naming "Spec"Class names use the Uppercamelcase style and must be in the Hump form, except for the following: (related naming of domain models) do/bo/dto/vo. Positive Example: Marcopolo/userdo/xmlservice/tcpudpdeal/tapromotion Counter Example: Macropolo/userdo/xmlservice/tcpudpdeal/tapromot Ion "Spec"Method names, parameter names, member variables, and local variables are uniformly used in lowercamelcase style and mu
