Answer 3

There are no stupid questions, only stupid answers.
So I'll try not to give you a stupid answer.
API stands for Application Programing Interface. You may find some info about it here: https://en.m.wikipedia.org/wiki/Application_programming_interface.
I guess a previous knowledge in HTML or Javascript could help you a lot understanding.
I myself am struggling to understand many concepts and I guess I will study some html and Javascript before reviewing again some parts of this lesson.
Good luck!

Answer 4

I could change ...like a name? what's this object function?
during the lesson about API, it keeps showing I show learn JAVA first, and I still can't understand what API stands for.
