AMD (Asynchronous module definition specification)

AMD Spec:Https://github.com/amdjs/amdjs-api/wiki/AMD

This specification defines only a function "define", which is a global variable. The description of the function is:

Define (ID?, dependencies, Factory);

The first parameter, ID, is a string. It refers to the name of the module in the definition, and this parameter is optional. If this parameter is not provided, the module name should default to the name of the specified script requested by the module loader. If this argument is provided, the module name must be "top-level" and absolute (relative names are not allowed).

The second parameter, dependencies, is an array of modules that are dependent on the module in the definition. The dependent modules must be executed according to the factory method precedence of the module, and the results of the execution should be passed in as parameters in the factory method of the module in the dependency array, in the order of the arguments.

A third parameter, factory, initializes the function or object to execute for the module. If it is a function, it should only be executed once. If it is an object, this object should be the output value of the module.
