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.
- 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. - 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. - The
break
statement terminates the loop prematurely. - The
continue
statement skips the current iteration and proceeds to the next iteration. - We can use the
break
andcontinue
statements for bothwhile
andfor
loops. - We can iterate through characters in a text using a
for
orwhile
loop. - 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.
