Another great explanation @tapas. Now I understood that map, filter, find are actually HoF. and thank you since you explained the concepts of functions very well in the previous videos, now I can easily follow. Also the concept of callback function is now clear to me.

Hi Tapas ! You said Higher Order Functions takes functions as input or return a function. im confused that its not returning the function as its returning the result(the value)..can u pls clarify me

As I mentioned, a function takes a function as an argument and/or returns a function is a HoF. Not necessarily, it has to do the both. When I explained the definition, I emphasized this. The example I showed is the one that takes the function as an argument. So it is HoF. If a function just return a function but doesn't take a function as argument is still a HoF. I hope it is clear now. Btw.. Think of a usage that returns a function from a function. Let me know 😀
