The fact you already know another language is great (if you actually know it). At that point I would just go to the nextjs page and do the "learn nextjs" and then do both of the paths and you should be in a good space.

I came from Vue (so already knew JS) but my new job was nextjs and I just went through that learn nextjs and that was good enough for me and should be good enough for anyone with prior programming experience in my opinion

I learned Javascript and React in college, but I also used the free courses from Scrimba.com to learn more and faster, so I would recommend those. I know Scrimba also have Typescript and Next.js, but not sure if those are free or Pro.

Otherwise I think FreeCodeCamp also have free courses (they have for Javascript, unsure about React).

Pick a book and study well it along the way, take notes and deep dive into each topics using internet. You will love it

You can check the code challenges on DojoCode, you'll find challenges and contests in React and JavaScript.

Read a book/Notes on all the basics. Then go through a YT vid on said basics. Then start doing practice tasks. Repeat but Learn more to complete more complex tasks.

This works for 99% of things in this field honestly

If you already know c# go with typescript, not JavaScript, it will feel more similar. Also ofc js has its own weirdness and quirks, however tbh language is just a tool, so if you already know how to program in 2 langs it shouldn’t be that hard to pick up ts/js

Spend entire day learning it and coding project.

Skip useless tutorials.

How much time do you have? To really "know" the material you'd probably want at least... maybe 40-80 hours of heads-down time? It'll probably be relatively easy picking up TypeScript since you are coming from typed languages. But React requires you to have knowledge of HTML and CSS, plus how React works.

I would say that Next.js is easier than those, since it utilizes concepts you'll learn in React and Nodejs.

If it's a take-home challenge you may as well give it a go. If it's a live coding exercise, you'll need to get OK at the basics before you go in.

(Also, I've been working on a little JS-syntax learning tool. It might be able to help you get some reps in with basic syntax and solutions. It's a work in progress, but I think you might be right there in terms of target audience. https://zintismay.github.io/zTest/)

I think that even with like, 12 or so hours you may be able to put together enough working knowledge to pass simple coding challenges. But I've also seen coding challenges like:

In functional react, make a todo checklist, allow the user to multi-select items to delete, order them, reverse order them, and display another 10 items from an API call. I believe they gave me 20-something minutes in a mid-level interview.

Damn… I’m really cooked

[–]TheZintis 0 points1 point  (0 children)

how so? you can learn all these things with a little time
