Opening! Design and Implementation of JavaScript AMD module, javascriptamd
Open a trap and gradually learn and summarize JavaScript AMD specifications
First, let us put a simple implementation we have written, and then start to explain AMD from scratch, and how to implement an AMD by ourselves.

Recently in the study of CMD and AMD, on the Internet to see a good article, tidy up to see.In the early days of JavaScript development is to achieve a simple page interaction logic, a few words can be; now CPU, browser performance has been greatly improved, many pages logically migrated to the client (form validation, etc.), With the advent of the web2.0 era, Ajax technology has been widely used, jquery and other front-end libraries emerge, the front
1, Commonjs
COMMONJS is a specification of JavaScript modular programming, mainly in the modular specification of the server side, a single file is a module. Each module is a separate scope, and variables defined within the module cannot be read by other modules unless defined as the properties of the global object.
There is a global method require () in COMMONJS to load the module. The COMMONJS load module is synchronized, so only the load completes to perform the subsequent operation. Like Nod
"Sina Science and Technology," Beijing time July 7 Morning news, according to foreign media today, although AMD has repeatedly expressed no intention to enter the netbook market, but because the PC manufacturers use its chips to produce netbooks, AMD accidentally involved in this market.
Just two weeks after Acer's Gateway unveiled a netbook with AMD chips, Euro
If you've ever heard of JS modularity, then you should have heard or commonjs or AMD or even cmd, and I've heard it before, but I've heard it before. Now look at what these specs are, and why. A, COMMONJSNBSP;NBSP;COMMONJS is for the performance of JS to develop specifications, because JS does not have the function of the module so CommonJS came into being, it hoped that JS can run anywhere, not just the browser. commonjs can have a certain influenc
JS Module Specification (commonjs,amd,cmd), if you have heard the JS modular this thing, then you should have heard or CommonJS or AMD or even CMD these specifications, I have heard, but also really listen to it. Now look at what these specs are, and why.First, CommonJSCOMMONJS is for the performance of JS to make norms, Nodejs is the implementation of this specification, Webpack is also in the form of Comm
CommonJSCOMMONJS is a specification for server-side modules, and node. JS uses this specification.According to the COMMONJS specification, a single file is a module. The load module uses the Require method, which reads a file and executes it, and finally returns the exports object inside the file.For example://Foobar.js //private variable var test = 123; //Public method function foobar () { This.foo = function () { //do someing ...} This.bar = function () { //do someing ...}} the methods and var
The A88 motherboard is the 2014 AMD newly introduced motherboard, uses the fm2+ socket design, supports the FM2+/FM2 interface processor, supports the current AMD A10/a8/a6/a4/e2/athlon II X4 Each series mainstream processor, basically can say is the AMD Universal processor.
The A85 motherboard is a new motherboard introduced by
The bulldozer "is the core of AMD's radical redesign, and will become the next generation of AMD's High-performance processor technology for the client and server sectors, with an increase of 33% core and approximately 50% performance compared to the Opteron 6100 series."
As a new generation of processor architecture, AMD "Bulldozer" will adopt 32nm SOI technology, which makes "bulldozer" compared to "magny-cours" Hao long processor can increase the
script in the development of a wide range of applications, in this foundation combined with the COMMONJS specification, the front-end modular approach ushered in two scenarios: AMD, CMD.Borrow Sanzang mage A word: Man is a man's mother born, Demon is demon his mother born. This is not an elegant remark, but it is quite appropriate to use here. AMD is the normalized output of the module definition in the Re
The previous article learned what a module is, this article briefly describes how to define and load a module.I know three kinds of module loading methods are Commonjs, AMD and CMD online about these three kinds of module loading mode of the article a lot, I would like to do a brief introduction, if you want to know more about the internet to look at the relevant information. (1) Commonjs in Commonjs, a single file is a module. The called module uses
Recently I'm going to integrate some of the tools I wrote earlier into a JS library, but the libraries are both normal and not exposed to global variables in an AMD environment. It's a headache for a while. Then I refer to some of the current popular library source code. Learning to write a bit, it feels good.Now that we want to support AMD, we need to choose an AMD
AMD has been introducing high-performance new processors in recent months, including the AMD that we've brought before a10-7890k and AMD FX-8370 's evaluation. It is not hard to find from previous new products that AMD's processors are more cost-effective than Intel's, where the infrastructure, power consumption, and DDR4 memory support are the main drawbacks. To
trying and improving, and CommonJS is an important organization. They proposed many new JavaScript architecture solutions and standards, hoping to provide a uniform guide for front-end development.
AMD specification is one of the most famous ones. Its full name is Asynchronous Module Definition, that is, Asynchronous Module loading mechanism. From its standard description page, AMD is very short and simple
Socket fm2+ Interfacethe socket fm2+ is a successor to the socket FM2 and can be partially compatible with the socket FM2 processor. Socket fm2+ is the latest AMD Desktop platform CPU socket, the third generation Apu, compared to the second generation FM2, only two more pin support, PCIe 3.0 and unified addressable space, fm2+ motherboard October 2013 has been listed. Socket FM2 Interfacesocket FM2 is the CPU socket on the
Webpack: difference between require. ensure and require AMD, require. ensureIntroduction
Difference between require-ensure and require-amd:
Require-amd
Note: similar to AMD's require function, a module array and callback function are transmitted during use. The callback function is executed only after the modules are downloaded and executed.
Syntax:req
Know that JS has modular development, but also occasionally heard the name Requirejs,amd,cmd and so on, even when using node, but also used require and other methods, but there has been no clear understanding and concepts. Presumably this is a common condition for many novices who have just come into contact with this knowledge. In fact, just do some basic work, do not need to have too much understanding of them, know how to use on the line, what he i
AMD Brief Introduction
AMD is the abbreviation of asynchronous module Definition, that is, asynchronous modules loading mechanism. The specification is an API specification of asynchronous dynamically loaded JavaScript code, proposed by COMMONJS. AMD is a simple and elegant way to get a lot of mainstream JavaScript framework in favor of the mainstream JavaScript
