Pure ESM package

The package linked to from here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

FE vs BE

TL;DR enough of this kind of nonsense

---

I've been in the field for ~20 years and started as BE developer, and this is a reference for people thinking that because they are on the BE side, they're somehow entitled to:

• earn more money
• feel superior about FE developers
• joke about JavaScript or minimize the FE effort in any way

FWIW: I didn't produce the content presented here (the outline from Edmond Lau's book). I've just copy-pasted it from somewhere over the Internet, but I cannot remember what exactly the original source is. I was also not able to find the author's name, so I cannot give him/her the proper credits.
