The for loop is most appropriate when you know exactly how many times you want to iterate. Its structure of initialization, condition, and update expressions makes it ideal for counting up or down a specific number of times. For example, for(let i=0; i<10; i++) { ... } will execute exactly 10 times, with i going from 0 to 9. While you could use other loop types for this, the for loop's compact syntax and clear intent make it the standard choice for such predetermined iteration counts.
