One of the key differences between them is that with a for loop, you know exactly how many times that loop is going to perform its operation before it even runs. Some languages do this by creating a variable that will count up to a certain value and for loops can also be used to iterate through items in a list. That list will have a certain number of items which will be the number of times the for loop executes. With a while loop, you don't know how many times a loop is going to be executed. Instead, as the loop is running, it's constantly checking and checking for a condition to determine whether or not it should execute one more time. I'll use loops to help me perform a complex operation that I'm very familiar with, doing the dishes. My kitchen is a little bit of a mess and I want to clean it up before my…
