Learn to repeat tasks in a controlled way with `for` and `while`, understanding what is repeated, when it stops, and how the changing value evolves on each iteration.
A loop prevents you from copying the same action many times when only the state of each repetition changes.
If you want to show the numbers from 1 to 5, you could write five `console.log()` statements. But that does not scale and does not teach the program how to repeat with intention.
A loop solves that: it defines a repetition, a control rule, and a stopping point.
A `for` loop fits well when you have a clear counter or a planned number of repetitions.
`while` is useful when repetition depends more on a condition than on a fixed count.
In this case the program keeps entering the block as long as the condition remains `true`.
Because the state update happens inside the block, it is even more important not to forget changing the control variable.
The typical failure is not the loop itself. It is losing track of what makes it advance and what makes it stop.
