Use RequireJS in JavaScript applications for delayed loading and requirejs for delayed Loading
Both simple and complex Web applications are composed of HTML, JavaScript, and CSS files. Developers usually use third-party JavaScript frameworks such as JQuery, Knockout, and Underscore to speed up development. Because these JavaScript frameworks are developed for specific purposes and have been "verified", it i
With the website features gradually enriched, the page JS also become more and more complex and bloated, the original through the script tag to import a JS file this way has been unable to meet the current Internet development model, we need team collaboration, module reuse, unit testing and a series of complex needs.Requirejs is a very compact JavaScript module loading framework and is one of the best implementations of the AMD specification. The latest version of
Detailed description of modular development instances using Requirejs in Html, and requirejs instances
When the front-end is modularized, not only js needs to be modularized, but html also needs to be modularized. Here we will introduce how to implement modular development of html code through requirejs.

Introduction to RequireJS
RequireJS is a JavaScript module loader. It is ideal for browsers. Using RequireJS to load modular scripts increases the speed and quality of code loading.

Now let's take a look at the neat features of RequireJS:
The following is an html page:
At most one script statement introduces the require. js file and specifies another js file: config. js in data-main. Its definition is as follows:
require.config({ paths: { "jquery": "../third_party/jque

I recently read the requirejs source code, which is complicated (compared with seajs). I have compiled the flowchart of the main logic parts. If you are interested, please refer to the following link for criticism ~

A Why do you use Requirejs?
With the development of the project, JS files more and more large, need to be divided into JS files.
First of all, the above way when the Web page load, the browser will stop the rendering of the page, the more loading files, the Web page will lose the response time longer;
Secondly, because of the dependence of JS files, we must strictly ensure the loading sequence, the most dependent module must be put to the final l
