I think you accidentally explained the LRU cache by showing LFU logic (counting the number of times the item is called). Other than that, great content!

Hey man, just stumbled across your channel a couple weeks back and, wow.

You're probably the one single channel that strikes the balance between channels that does "hello world" tutorials and extremely deep content that tends to get a little dry.

I'm a mid tier software engineer with about 4 years of experience, and these videos couldn't come at a better time.

Keep up the good work!

hi @Guseyn, Thanks a lot for explanation. I am really liking your detailed videos like memory management, dependency injection etc. please please keep doing these videos as not much of info available on these things. I would really love if you make more videos on performance and security .

Thanks for the video.
I was hoping to see how you implement cache eviction policy using least frequently used pattern.
Nevertheless, nice video

Hi @SoftwareDeveloperDiaries, I really enjoyed your explanation. It will help me to debug a problem in my new job. By any chance, do you have the code you showed us?
