Hey everyone! I'm trying to wrap my head around loops in JavaScript. Can someone break down the differences between for loops and while loops? Also, when should I use one over the other? Are there other types of loops I should know about? Thanks!

So, here's the deal: a `for` loop is perfect when you know exactly how many times you want to run your code. For example, if you're stepping through an array or a range of numbers, this is your go-to. On the other hand, a `while` loop is better when you don't know how many times you'll need to loop—it continues until a specified condition is false. For instance, you might keep looping until user input meets certain criteria.
When you want to use a `while` loop, think about situations where you're checking something repeatedly, like monitoring a state. Remember that `for` loops can still be versatile for various structures beyond just arrays, which is pretty neat!
That makes sense! It's also cool to know that `for` loops can be used in setups like linked lists, not just arrays!
