At the end of the article she asked for our thoughts on that when she could've easily told us why 😂
I'll share mine though it may not be 100% accurate so I think that where we should be adviced on clearing a cache is when it is stored on the In memory or RAM. Though the eviction strategies may have their time of cache clearing but each item stored in the cache may take up a significant amount of memory space in the RAM and we should not forget that there are other tasks/applications that require space in the RAM too so if that space gets filled up the device tends to lag. That's why I think we need to clear it sometimes 😅
I am still trying to find out why we need to clear our cache ourselves
I left that question as a call to action hopefully we get answer, but I would still make my research
