Drawbacks of the namespacing patternreliance on a single global variable to be the application ' s global. In the namespacing-pattern, there is no-to-have-versions of the same application or library run on the same page, Because they both need the same global symbol name, for example, MYAPP.long, dotted names to type and resolve at runtime, for example, MYAPP.utilities.array.A Global ConstructorUsing The sandbox would look like this:New

the sandbox mechanism (sandbox) in iOS is a security system that specifies that an application can only read files within a folder created for the app and cannot access content elsewhere. All non-code files are saved in this place, such as slices, sounds, attribute lists, and text files. The application sandbox typically includes the following file directories:
