It's that time of the week again, just a day early. I'm off tomorrow and Monday so posting this now.

So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

Information flowing through your brain

Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.


Summarize a concept that is new to you.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.πŸ‘‡πŸ‘‡πŸ»πŸ‘‡πŸΌπŸ‘‡πŸ½πŸ‘‡πŸΎπŸ‘‡πŸΏ

Editor guide

This week was a productive one!

  • I improved last week TypeScript unit testing
  • Created particles emitters

  • Learnt about Spatial Hash Maps to improve performances of particles (w/ help of another contributor)
  • Fixed the collision system that was just random, now it has math 🀣

  • Created particles absorbers (black holes)

  • A lot of refactoring and bug fixing, but it's not much exciting 🀣

Learn how to use Docker to build image with card driver, Google Chrome with head browser, Personal Certificate Client and Heath ID card client.

That's awesome! πŸ”₯

Yes, that's awesome!


This April, I did my first Stream on Twitch where I (tried) to teach people about Security.
That was so much fun. I learnt a lot about Pyblic Speaking, etc.. And loved it.

I am planning to do that a lot more.
And I can't encourage people not to do that because when you are talking about something, you definitely have to know it properly. So it can bring you a lot as well.


I learned how to use git rebase!.
And now I've improved my workflow!


In your opinion, what is the advantage of git rebase over a standard push/merge/pull


You end with a linear history, that for me it is cleaner. Because, from my point of view, is clearer to view the history of the project making easier to track changes, issues, bugs.

When I only used "git merge", I was getting really frustrated about reviewing the project history.
If you don't use it, I suggest you check it.


I learned how to write clean and understandle code with proper commenting, variable and functional naming.. plus git comments..


I implemented the offline storage of our react application with IndexDB - never worked with it. quite cool!


Redux and React! Well, I knew about them before this week, but they make so much more sense now. I was stuck on state, props and setting up the Redux store for a while


That's awesome! πŸ”₯

Yes, that's awesome!


I learned about web components and the shadowDOM! I also learned not to overload myself too much with learning and keep a comfortable place to not feel the burn out :)


I learnt about JS closures, scopes, this and that.... and other ES6 cool stuff!


I got myself a Rubik's cube 2 days ago and learned how to solve it using the 3 layer method. Next up speed improvements, then moving on to more advanced solving techniques.


I hope this week will bring good results to a lot of things that I did this week.


This week i learned about routing in react, and how to have a multi-page-feeling in a single page application.
