Really like this style of lesson. It feels like there could be a whole "cardio" spinoff series. Short and sweet with a lot of value. Looks at some, every, find, and findIndex array methods as well as the ... "spread" operator and ES6 style ways to remove an element from an array.

Probably mostly refresher if you've got any experience with either underscore or lodash - but always nice to see how to do the same thing in vanilla JS.

Completion Time: ~10 Minutes.
