Sandbox mode can compensate for two deficiencies in the namespace pattern:
Using a unique global object as a global variable entry for a program makes it impossible to use two different versions of the API in the same program, so they use the same unique global object name, such as MyApp;
Longer nested objects make code writing and parsing slower;

JavaScript itself does not provide a namespace mechanism. To avoid global space pollution caused by different functions, objects, and variable names, the common practice is

When the AdobeFlashPlayer plug-in is updated to 11.3, the sandbox feature (protection mode) is added to enhance the security of the browser. However, adding this technology requires more resources, it also makes the running of AdobeFlashPlayer more unstable. The Sandbox feature has not been applied to AdobeFlashPlayer for a long time. Since it is unstable
