Modules/Wrappings makes implementation a reality. Although it is not exactly the same as the node. js module writing method, there are also many similarities, so that programmers familiar with node. js have some intimacy.
But NodeJS is the JavaScript on the server end after all, and there is no need to put these lines in the browser's JavaScript environment. At this time, AMD was born, and its full definition is called asynchronous module. It is known
AMD, CMD, COMMONJS specificationThe idea of splitting the JS code into small chunks with different functions is popular in some tripartite specifications, such as COMMONJS, AMD, and CMD. Let's take a look at these kinds of specifications.
I. Modular specificationCommonjs is used on the server side, is synchronous loading, Nodejs is the practice of this specification.Amd,cmd is used on the browser side

The modular development method can improve the code reuse rate and facilitate the management of code. Usually a file is a module that has its own scope, exposing only specific variables and functions to the outside. The current popular JS Modular specification has COMMONJS, AMD, cmd and ES6 module system. The evolution of the front-end modularity can be seen in the Nanyi teacher's article. This paper mainly introduces the modular realization mode unde
, because the module's JS files are on the local hard disk, the CPU read time is very fast, synchronization is not a problem.But in the client browser with COMMONJS load module will depend on the speed, if the use of synchronization, network sentiment is unstable, the page may be stuck. The AMD Async module definition is therefore present for the client.AmdAMD (asynchronous module Definition) asynchronously loads the module. The
For large Web applications or projects, tens of thousands of lines of code, to develop and post-maintenance has brought great trouble. Therefore, a standardized module management mechanism is needed to help developers centralize the definition and invocation relationships of the modules.Before the official launch of ES6, there have been a number of people committed to the introduction of web development for the modular management standards, CommonJS, AMD

AMD is the abbreviation for "Asynchronous module definition", meaning "async module definition". AMD defines that the modules we use are all asynchronously loaded, so we're going to put the code fragment of the dependent module in a callback function, and when the asynchronous load module is complete (that is, when the module is available), trigger the callback function. The commonly used
Many new JavaScript architecture scenarios and standards have been proposed by COMMONJS to provide unified guidance for front-end development. AMD specification is one of the more famous, the full name is asynchronous module definition, that is, the asynchronous module loading mechanism, the complete description of the module definition, dependency, reference relationship and loading mechanism. The AMD spec

Chip Industry analysts said on Wednesday that intel is lagging behind AMD in terms of producing the most powerful processors. Intel last week announced the abolition of the 4G Pentium 4 Development Plan, and AMD on Tuesday launched athlon 64 FX-55 and athlon 64 4000 + two chips, analysts believe that AMD's new chips will be welcomed by the high-end PC market.

Introduction to JavaScript AMD specifications (1)AMD stands for "Asynchronous Module Definition", which means "Asynchronous Module Definition ". AMD defines that all modules we use are asynchronously loaded, so we need to put the code snippets of the dependent modules in a callback function, after the asynchronous loading module is complete (that is, when this mo
CommonJS and AMD and RequireJS? In the past, CommonJS had a Modules specification. It was very difficult for us to write everything like JS in a file to write the server-side application, it is used to solve JS's lack of modular code management function. The key part is two functions: require-used to introduce dependency export-used to export modules, including identifier and contents CommonJS is not just a specification, just like interfaces in Java

Specification of modulesFirst think about why the module is important?Because of the module, we can more easily use other people's code, want what function, load what module.However, this has a premise, that is, we must write the module in the same way, otherwise you have your writing, I have my writing, it is not messy set!
