we can also implement caching when the user clears and backspace so it won't make again api calls it will fetch the data from cache

Hello sir, I want to ask, how does Instagram infinite scroll works in terms of rendering the post artciles in the DOM? I think its called virtualized lists, but I just couldnt understand how they implemented them. They have used padding top and padding bottom for this, but it went all over my head. Do you mind explaining this sometime on one of your future videos?

optimization in typeahead system i think would be more on the storage strategy.. where we can decide on how to cache commonly suggested results for user inputs, deciding on which data structure (tree, dictionary etc) would best support in storing closest words with the prefix coming from user input etc. so the suggestions are more accurate & can be fetched faster (similar to indexing in db). And to make this decision we need to estimate the traffic, requests possible/sec. It will require an understanding of even backend.
P.S : I'm just typing as im thinking not sure how right i am at thinking these.. i know no theory or jargons in system design.

Correct ! one of the right approach

[@yashpatel1129]

we can use caching for auto suggestion functionality. something like LRU cache

Correct ! one of the right approach
