Some JavaScript coding specifications

For Engineers familiar with C/C ++ or Java, JavaScript is flexible and simple.

For Engineers familiar with the C/C ++ or Java language, JavaScript is flexible, easy to understand, and requires relatively loose code formats. It is easy to learn and use it in your own code. Because of this, JavaScript coding standards are often despised. Fixing and complementing during the development process will eventually become a nightmare for subsequent maintenance personnel. The long-term value of software is directly proportional to the coding quality. Coding specifications can help us reduce unnecessary troubles in programming. While JavaScript code is directly sent to the client's browser and directly met with the customer, the quality of code should be paid more attention.

This article describes the coding standards in JavaScript programming and analyzes the reasons. It is expected that more Web developers will pay attention to JavaScript coding standards and software product quality issues.

I believe many engineers are not unfamiliar with the C/C ++ and Java coding specifications. However, when it comes to the JavaScript language encoding specifications, you may not be able to help. Isn't JavaScript syntax flexible? Variables can be declared at any time; statement Terminator can be avoided; string and number can also be added; one or more parameters will not report an error. Yes, when you switch from the strict C/C ++ and Java syntax rules to the JavaScript language, you will feel a lot of freedom and much easier. Loose syntax is an important feature of JavaScript. It is flexible and easy to understand, and brings a lot of convenience to developers. However, if you do not pay attention to the coding process, the debugging and maintenance costs of the code will be invisible.

JavaScript code will be directly sent to the browser on the client as needed. The code specification not only guarantees the code quality, but also affects the long-term reputation of the product. We hope that the standardization of the JavaScript programming language will also attract more attention from friends.

This article provides some suggestions for the formatting, naming, declaration, scope, and use of some special symbols involved in the JavaScript coding process, and analyze the reason for reference.

JavaScript file reference

JavaScript programs should be stored in. js files as much as possible.
