Back end development can seem intimidating to those who haven't done it yet, but there's no reason for that. Back end development, in my opinion, is only considered harder because you aren't seeing change happen on the screen. It requires just a little bit more patience. Most of the internet is made up of C.R.U.D. applications which stands for create, read, update, and delete. To summarize this kind of application in one sentence, it can take data from the user, store it in a data base, edit the data, and return it to the user. For those new to development, I highly suggest making one as an intro to full stack or back end development.
For example, I made a fitness tracker with React. However, whenever I refreshed the page all of my exercises and workouts were gone. What I wanted to make was something you could log into from anywhere in order to log your exercises. In order to learn the skills to do so I followed along with Traversy Media's M.E.R.N. stack series which was about 13 hours of video, most of which I had to watch twice or pause to catch up with coding. Whichever stack you pick isn't terribly important but it should sync well with the front end framework you are using. Your stack will likely include Node.js, a modern back end also made with JavaScript (previously unheard of).
Think of a way to make your stack a full stack project and begin using your resources to learn the skills to do so. Do not under any circumstance just copy a tutorial and decide you've learned the skills. Apply it to your own project in some way, shape, or form. In my eyes, making a full stack project earns you your official developer badge. It doesn't necessarily mean you're a good developer, but you've taken off the training wheels. Now that I've covered how I learned to code I will begin posting about how I am becoming a better developer. Topics will include security, comments, optimization, and more. Thanks for reading.
