About the namespace namespace pattern in JS

Namespaces help to reduce the number of global variables required in your program, and it helps to avoid naming conflicts or too long prefix names.

An example of a namespace:

1 /**2 * Create global object MyApp3 * @module MYAPP4 * @title MYAPP Global5 */6 varMyApp = MyApp | | {};7 8 /**9 * Returns the specified namespace, or creates a namespace if the namespace does not exist. Ten * Note: Be careful when naming, keep keywords in mind, and may not be available in some browsers.
