-The first two we used a method called `.map()`. This method lets you do something to every item, then pass it on. The last one we used called `.for_each()`. This method just lets you do something to every item. `.iter_mut()` plus `for_each()` is basically just a `for` loop. Inside each method we can give a name to every item (we just called it `x`) and use that to change it. These are called closures and we will learn about them in the next section.
