API stands for "application programming interface". When I was first introduced to APIs, I had a hard time comprehending its concept. I did not understand how APIs contribute to web development and modern-day software. Reading Educative.io's article on APIs helped me to better understand APIs.

APIs require an ID token to access. There are public APIs on the web and anyone is free to mess with them, they can teach you a lot about your language’s syntax and programming concepts in general.
