Debouncing:

tying slow = 200ms typing fast = 50ms

Performance: searching - iphone pro max = 14 letter * 1000 = 14000 with debouncing - 3 api calls * 1000 = 3000

Debouncing with 200ms

• if diff b/w 2 keystrokes is <200 - decline API calls ->200 make an APT Calls

time complexity to search array = O(n) time complexity to search map/object = O(1)
