Potential "Learning" page revised contents

[markerikson]

The "Learning" page really hasn't been touched since like 2016 or something, and a lot of material has changed since then.

I put together a "front end learning resources" list for my day job somewhat recently, and I'm going to dump that material here as a potential replacement for the current contents.

I don't want to replace the existing page right away, because there may be some stuff in there that I've forgotten about and is worth keeping. Also, the two lists are formatted differently. But, here you go:

Recommended Learning Path

You should learn these technologies in the following order:

1. "How Web Apps Work": a series of posts that lays out the big picture of the core technologies, terms, and concepts used in client/server web apps
2. JavaScript . If you don't know JavaScript, nothing else will make sense
3. React . You can use React by itself, or with Redux and/or TypeScript. Learning it separately will minimize the number of new concepts and syntax you have to learn at once.
4. Redux . Redux can be used separately, but it's most commonly used with React.
5. TypeScript . Because it adds static types on top of JS, you need to understand JS first. Also, it's easiest to understand React and Redux first, then learn how to use them with static types.

The resources in this page are listed in that order.

You are not required to read every single link and article listed in this page. However, you should try to read through as many of the articles linked in the "Recommended Primary Resources" sections as possible, especially for topics you are not already familiar with. Many of the recommended tutorials do cover the same topics, so feel free to skip past concepts you've already learned.

Links in the "Additional Resources" sections are available as references and reading as needed.

React

Recommended Primary Resources (should read)

General React

Start with reading the official docs first. However, the React team is in the process of starting a major rewrite of the React docs site to focus on teaching function components and hooks first. That won't be published until mid-2021. Until then, a third party has made a fork of the React docs and converted the tutorials and examples to show function components instead of classes, so I'm going to link that here and suggest reading it.

These other listed tutorials are also excellent and may explain things in a different way.

• Read: official React docs

  • Getting Started (docs overview and related resources)
  • Main Concepts (read the whole series, but especially these two):
    • Lifting State Up
    • Thinking In React

• Read: React docs (converted to show hooks)

  • Tutorial

• Watch: React Tutorial for Beginners

• Read: Intro to React, Redux, and TypeScript for 2020 (Mark's presentation slides)

• Read: Build a CRUD App in React with Hooks

• Read: A Comprehensive Guide to React in 2020

Project Setup

• Read: Simple React Development in 2019 (a guide to setting up an app, development environment, and deployment)
• Use: CodeSandbox.io (an online IDE that uses VS Code's editor, and can let you develop and run your apps completely in the browser)
• Use: Create-React-App (the official CLI tool for creating a React app with one command. Sets up a project with good default build settings out of the box.)

Specific Topics

• Understanding how React works conceptually / internally
  • React as a UI Runtime (deep dive - not required reading, but will definitely help you understand React better)

@markerikson do you want to make a PR with the updated content you shared here plus the content you want to keep? I can announce the updated section on twitter or in the announcements so people know

[leni1]

@markerikson @vcarl the link for 'A Comprehensive Guide to React in 2020' in the React's Recommended Primary Resources section redirects to a 404 (the original was on Medium which freeCodeCamp switched away from). Could either of you take a look and see if this is the article you meant: https://www.freecodecamp.org/news/a-complete-beginners-guide-to-react-4d490abc349c/

If so happy to open an MR to add this because this outline has been of great value to me and I would glad give back 🙏🏿 Thanks 😇

[markerikson]

@leni1 : hmm. Annoyingly, the Web Archive doesn't show the original version due to 302 redirects.

Googling the URL, I found https://twitter.com/instaworldcode/status/978189785935343616 , which suggests it was actually by Tyler McGinnis.

If that's the case, the article probably also disappeared after he set up the UI.dev course site.

The article you linked to seems too out of date to use as a replacement.

Anyone have suggestions for a better article to replace that link? (Or we could just remove it, especially since the React beta docs exist now)

[vcarl]

I'm going to close this after #200 and #201, if there are content issues with links and such we'd love PRs though! With this many, it wouldn't surprise me if some slip past
