I'm excited to get you up and running with APIs! Before we make a demo app with an API, we need to learn.
You can add a robust search to your site with Algolia's API or a complete shopping experience with Snipcart. When you learn how to use an API, you're able to use services that would otherwise take you a long time to code yourself. Or you could just start integrating APIs and give your code super-powers. You could go about writing all those jokes yourself or copying and pasting them into a file for your site to read from. Do you want to be able to pull in weather data for your users? Get them the latest sports scores for your app? Want to make a site that tells your user a random joke, or create your own Pokedex?
