Episode notes

Promises is a feature of JavaScript, but it's also a concept here. Most things in JavaScript are asynchronous meaning that you say go get bread but that function does not hold up the Rest of the JavaScript from running like Scott said. When you do something asynchronously you can just fire it off and Keep doing something else While that is working while Scott's going to the store to get bread So that's whatynchronous means And then the opposite of a synchronous is synchronous meaning that You do one thing after another.

In this Hasty Treat, Scott and Wes explain more buzz words like schema, promises, async, sync, dom vs shadow dom vs page HTML, props, and more.
