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.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

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 🤣

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.

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.

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

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 :)
