My main thing was how all of the functions and variable and all of those pieces would eventually create an app.

Ok, that makes sense, so you practically have to think of everything in pieces and how everything goes together. Just one last question, how is an app like Instagram built? (Thank you for replying and supporting me! I’m in high school and have had an interest in coding for a while and finally decided to learn, and maybe will do something in college revolving around it!)
