Framework is like Lego. It provides you pieces you can use to build something.
Library is a set of very specific Lego pieces. Pieces that didn't exist in your original set of Lego.
API is when you have built a house with Lego and you need Lego guys to live there but you don't want to teach them how to behave (lol this metaphor isn't ideal probably :D)... BUT there's someone out there who built entire city with Lego, including Lego guys. This person is letting you borrow their trained Lego guys and use in you own project...

OMG!Thank you very much! The example was very helpful 😄
