Happy Pi Day one day early awesome community members!
It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.
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.👇👇🏻👇🏼👇🏽👇🏾👇🏿

I updated the social card generator on my gatsby blog website so that two separate images would be automatically generated - one each for Twitter and DEV (since they have different dimensions). I also made so that you could pass in an image URL and it would use it as the background:
I followed this tutorial here if anyone else is interested in adding it to their gatsby site!
Nice!
This week I learned Pure components in react and wrote below article about the same.

Also spend some time on Azure functions.
Some object-oriented design patterns, by browsing Github open source :)
Service workers. A little bit complicated with their 3 step lifecycle, but fairly nifty. Mostly from the Google developers service workers primer
Service workers are fun! Tricky, yes, but fun!
I just started in a new company this week. I have just transitioned from functional business analysis to data analytics and data warehousing. I am just learning how the data is structured and starting a new project in Python, SQL and Airflow with BigQuery.
Awesome! Sounds like it would make for a great post on DEV. 😉
Learnt Wepack and how does it work
Ruby on Rails! Decided to take the plunge and start taking the BE stack we use seriously this year. 💪💪
Well, it's kind of weird saying that but I've been working with JavaScript for a while and yesterday I had to write a class. I had actually never written one in JS, mostly doing functional programming. The task at hand just felt more natural using a class.
So I learned about the intricacies of class variables, properties and methods. I got a lot of "unexpected..." or "undefined..." errors until I got the syntax right. That first JS class tutorial I looked at had a lot of errors in it. lol
I also found that I had to be careful about the syntax of a callback passed to findIndex (for arrays). I wasn't getting any error but always got a -1 result until I found that the syntax there was... hmmm... a bit simpler than what I've been doing for things like event listeners.
All frustrating at first, but in the end it all worked and it's a win. :)
Finally succeeded doing an interactive rebase! I used to just trash a branch and create a new one. This time I actually read and understand how it works.
Nice article: blog.algolia.com/master-git-rebase/
Nice Lenny! Hope all is well! Say hi to the Shotgun peeps for me! 👋
I got to know more about React/Redux by reading some of the questions listed in this repo.
