Does anyone have any opinion on whether I should spend time learning Deno and Typescript instead of digging deeper into what I already know? I find it hard to tell if Deno will start showing up in job descriptions in a few years, or if Node is so entrenched that it would only distract me from building on my current skills.
Deno is not relevant enough, I would wager 99.99% of the existing projects you might find yourself working on in the next few years will be using node somewhere in the stack. It shouldn’t be hard to pick up deno when it eventually does show up.
You can safely ignore Deno for the time being.
It also keeps me more honest because I’m not going through the trouble of typing a parameter or variable just to make it any.
1. Clément Mihailescu has a good summary done in less than fifteen minutes.
2. FreeCodeCamp.org has a long video.
Learn how to use Typescript, it's pervasive in the JS ecosystem and very easy to learn now.
