localStorage is a very useful way to store data. I think calling localStorage on every request (operation) will cause performance problems?
is it necessary to use variable storage instead ( localStorage.getItem ) only if the page is refreshed and the variable expires?
Synchronize iMaguo operation, Although it is saved on disk, this read and write does not seem to affect performance. Some browsers will temporarily store the localStorage operation in memory until you close it and then read and write the disk. So during this period, there should be no difference between localStorage operation and saving as a variable
frequent operation of localstorage for a short period of time can cause stutters or rendering process crashes, such as electron. The specific amount of time varies from browser to browser. The electron of the domestic operating system mips is more sensitive and prone to crash
it is recommended to use indexdb to store things with large capacity and frequent operation
recently I encountered this problem. Operating localstorage frequently for a long time will cause stutters and crashes in electron. Solid hammer. My solution is to implement a memory-based localstorage instead.
in the interview question of one of the three major factories more than half a year ago, the interviewer asked what to do if the capacity was found to exceed when writing localstorage (that is, the general standard of 5m). At that time, he was rather ner...
