3.3: Fetch in JavaScript

Axios is a popular Javascript library that can be used instead of fetch. It is a promise based HTTP client. Postman is a popular tool for testing REST API’s.

3.4: The Cloud

3.5: Firebase

Note that Firebase Firestore is a NoSQL database. As a brief overview, databases can be structured (like a table) or unstructured (like a document). In this lesson, we will be using unstructured data, but many of the concepts will be the same.

3.7: Firestore Walkthrough

3.8: Component Libraries

3.9: Async/Await

3.10: Systems Design

In the video, it states that Systems Design is section 9; this is merely a typo. Additionally, the links referenced in the video are linked above in external resources.
