+## XMLHttpRequests
+- What is an Http request?
+    - Life of a request
+        - https://dev.to/dangolant/things-i-brushed-up-on-this-week-the-http-request-lifecycle-
+    - REST
+    - Verbs
+    - Headers
+    - Status codes
+- Example w/ curl
+- Now how do we send a request with a browser?
+- Websites of the early era required a complete page load upon each request (https://en.wikipedia.org/wiki/Ajax_(programming))
+    - This is inefficient and provides a bad user experience with full reloads on each action. Example: MapQuest in the early days.
+- AJAX
+    - Gmail in 2004 and Google Maps in 2005
+    - A way for browsers to send requests asyncronously! 🎉
+    - In 2006, W3C releated XMLHttpRequest specification
+- XMLHttpRequest
+    - Guide: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest
+
+## API calls
+- Open API's without need for auth tokens (https://github.com/public-apis/public-apis/blob/master/README.md). Use one for example.
+- Create new HTML file
+- Create a button that will have an event listener
+- Retrieve data from api with XMLHttpRequest obj
+
+- ...but callbacks? [joke](https://www.reddit.com/r/ProgrammerHumor/comments/che938/asynchronous_javascript/)
