Reprinted: HTMl5 of Sessionstorage and LocalstorageThe Web Storage in HTML5 includes two ways of storage: Sessionstorage and Localstorage.sessionstorage is used to store data locally in a session, which can only be accessed by a page in the same session and destroyed when the session ends.

, it also belongs to the static data area. However, the data in this paragraph is not initialized. Uninitialized data segments are generated only during the initialization phase of the run, so its size does not affect the size of the destination file. In a program, there are generally no initialized global variables and static local variables that are not initialized.Additional Instructions:Constant Zone (special constant store, which belongs to the static s
