Iteration is essentially looping.
Loops generally involve repeating some code a certain number of times, or until a condition is met.
Types of iteration
There are two main forms of loops in programming languages:
- Count controlled: for loop or foreach loop
- Condition controlled: while loop or do while loop
Iteration and recursion
Recursion is a programming technique that often achieves the same thing as iteration. In some cases, it can be a better option than iteration.
