Loops Recap

In this chapter, we learned how to work with loops in JavaScript. We discovered that:

We use loops when we need to repeat a part of the code.

1. The while loop allows us to repeatedly execute a block of code as long as the condition is true. It is used when we do not know how many times the loop will need to be repeated.
2. The for loop also allows us to repeatedly execute a block of code. It is more intuitive for working with arrays and is used when we know how many times the loop will need to be repeated.
3. The break statement terminates the loop prematurely.
4. The continue statement skips the current iteration and proceeds to the next iteration.
5. We can use the break and continue statements for both while and for loops.
6. We can iterate through characters in a text using a for or while loop.
7. Loops can be nested, which means one loop can be inside another. This is useful when working with multiple arrays or with nested arrays.

Congratulations on completing the lesson on loops! In the next lesson, we will look at functions. They will help us write more efficient and readable code, which is essential for solving more complex problems.
