As described in question, there are around 320 area codes in the US. 10M is a very large number for the count of area codes. Would someone please help me to understand this assumption?
Hi @anqib48356, Thanks for reaching out to us.
In the lesson, it is mentioned that Let’s assume we are catering to users in 10M area codes but at the same time, it is also written that this number will grow. We assumed 10M areas initially to just calculate the rough idea about the storage estimation and initial total records of dishes.
So this is just the assumption for the sake of initial calculations.
Hope it will help you, Happy Learning
