Understanding APIs (Part 2): API Analogies and Examples

Updated: Sep 4



In Part 1 of this series, “Understanding APIs (Part 1): What is an API?,” we learned about the acronym, the definition, the four aspects of an API, and how everything works together.

When I look at practical examples of applied technologies, it can really open my eyes to understanding a theory. In the case of APIs, looking at different examples helped me get a better idea of this concept.
