Windows 10 version 2004 - Installing Node.js on Windows Subsystem for Linux (WSL/WSL2)

UPDATE (Fall 2020): This gist is an updated version to the Windows 10 Fall Creators Update - Installing Node.js on Windows Subsystem for Linux (WSL) guide, I usually just keep here notes, configuration or short guides for personal use, it was nice to know it also helps other ppl, I hope this one too.

Windows updated windows subsystem for linux to version 2, as the F.A.Q stated you can still use WSL version 1 side by side with version 2. I'm not sure about existing WSL machines surviving the upgrade process, but as always backup and 🤞. NOTE: WSL version 1 is not replace/deprecated, and there ar

Helper function

This function create a saga that runs the sagas in the startingSagas array and takes the actions with type indicated by changeActionType to replace the running sagas. The replacing actions must have a field sagas cointaining the array with the new sagas.

function createDynamicSaga (changeActionType, startingSagas) {
  function* _start (sagas) {
    try {
      yield sagas

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's
