Completely agree. Aside from learning the basics of the language (which if you already know any other "C like" language isn't difficult), gaining a good understanding of async flows (Promises then async/await) is absolutely key in JS and is probably the biggest hangup I see people run into. Where I work I'm considered the JS "expert", my coworkers consist of a few older seniors that mostly do backend work that think JS is bad/confusing language, and a few juniors that really only have experience with languages they learned in school (which probably doesn't include JS). And 90% of the issues I help them with are caused by a lack of understanding of async JS -- "why is this value undefined?" or "how do I get the data out of a Promise" and for the latter telling them "well, you don't get the data out of a Promise, you would chain it with .then(data => data) to operate/use the data" is usually met with even more confused looks. Though async/await helps a ton with how they use the data from a resolved async operation, you still need to understand promises (at least a little) since it's built on top of them (e.g. in a try/catch async block the lines after the await are essentially the function that gets passed to promise.then() and the lines in the catch block being the function that gets passed to promise.catch()). Two other things I'd like to mention (which could be under "learning the language") that I think really help with really understanding JS and being able to use it well are: 1. Understand the Event Loop[1]. Learning this will make a lot of JS's oddities make sense, and is something you should learn even before learning about async JS as it will explain how your async function actually works under the hood (i.e. the non-blocking nature of JS). 2.
