jQuery was a wonderful tool that paved over the irregularities of browsers and offered a simple interface for making very powerful applications. Today with evergreen browsers and modern JavaScript, we no longer need this crutch. Let's look at our favorite jQuery techniques like $.ajax() and $(...).click() and $(...).addClass() and compare this to the code we'd write in modern JavaScript. Sprinkled in are great ES6 techniques like rest and spread, promises and fetch. Challenge yourself on your next project to see if you can run in a post-jQuery world.
