In this chapter, we've looked at the difference between the HTTP GET and POST requests, and discussed where it's good to use which. Although we have no good use for HTTP POST at the moment, we will use it in future projects where we will be getting login data from our users. Luckily, the explanatory work we did with HTTP POST is not lost—we also took a look at some more advanced ways that Git can help us with version control, and our unused code is safely stored in a different branch of our code repository in case we need to refer back to it later. Last but not least, we added weather and currency data to our application, and looked at a few different options for allowing our user to input data into our application. We're nearly done with our first project!

In the next chapter, we'll do some cosmetic touch-ups, and look at remembering our users so that they don't have to carry out exactly the same actions every time they visit our site.
