the coding should be more attention.
This paper discusses the problem of coding standard in JavaScript programming, and analyzes the reasons. Expect more WEB developers to focus on JavaScript coding specifications and focus on software PRODUCT quality issues.

It is believed that many engineers are not unfamiliar with the reference to C + + and Java
Static languageWhen you write code, you must specify a specific type of language for the variable. such as Java, C + +Dynamic languageInstead of specifying an explicit type for a variable when writing code, the interpreter determines the type of the variable at run time, based on the usage of the variable. such as Python, JavaScript# python's dynamic characteristics m = ten'hello'print m #print ' Hello 'Strongly typed languagesThe variable must have a certain type. such as Java, C + +, Pytho

What are compilation languages, explanatory languages, and scripting languages?Computers cannot directly understand high-level languages, but can only directly understand machine languages. Therefor
the language does not need to compile, save the process, the explanatory language is translated when running the program, such as the explanatory Basic language, there is a special interpreter can directly execute the BASIC program, each statement is executed when the translation ; Such explanatory language should be translated once every time it is executed, and the efficiency is lower; (only translate when running the program, once per execution, translate once) (low efficiency)5. Scripting
Reply content:Before you write JavaScript, listen to people say that you don't have to ignore the variable type, just use it. Then various into the pits.
Clearly is the distinction of good, but only the language is not obvious, plus some less intelligent type automatic conversion.
Weakly typed languages are really good for getting started, but you can't ignore variable types if you want to be proficient.
In addition, if the problem can be solved outsi
We know that the encoding method should be declared in the header file of Python source code. If you don't just use ASCII code, many people may write a little different:
# Coding = UTF-8
# Coding: UTF-8
#-*-Coding: UTF-8 -*-
So how can we effectively write data? What advantages are ineffective?

1. Prediction code
CompressionAlgorithmThe essence is to remove redundancy between signals. What is signal redundancy? The correlation between signals is redundancy. human hearing or visual systems that do not feel or mask can also be used as redundant components. Today we will talk about the concept of predictive coding, which is a very intuitive and simple method. It is intuitive. Taking an image as an example, There Are similarity and correlation
Program languages can be divided into five categories
1. Web page script ages
Webpage code, such as HTML, JavaScript, CSS, ASP, PHP, and XML, should all belong to this class (according to Cai's meaning, HTML should not belong to anguages, maybe he thinks it is too simple, but I think HTML should also be counted. It doesn't matter who you like to listen)

I personally think that dynamic languages like Ruby are much simpler. I personally think that dynamic languages like Ruby are much simpler. Reply content: I don't think it should be static or dynamic, but strong or weak.
A strong type is less prone to errors than a weak type, while a weak type only saves some code.

The development of computer has promoted the emergence of a new profession. programmers have appeared in recent years and have gained a wide range of attention. I believe this is also the dream of many new students. But there are also many types of programmers, not every programmer can be proficient in all programming languages. The so-called specialization in the industry. If you are interested in the programming world in the future, you should pay a

Programming in such a language does not give the variable a type, but a data type when it is attached. For example, Python and Ruby are ty
