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 learned about the power of LinkedIn and using social media to build community! 🌎 I posted on LinkedIn about being accepted as one of AWS' Community Builders in the data category and in less than a week, my post has been seen by 49,000+ people so far.
It was an especially cool experience because it has prompted a lot of interest from my network, mentors, mentees, and friends who want to know how to get into tech, coding, software engineering, and app development. I'm actually looking to launch a YouTube channel this month because of this. #ThePowerOfContent
Nice!
This week I can't find time to learn anything 😭
Nothing wrong with that.
CSS * is closer to RegEx . or RegEx + than RegEx *
I'm pretty sure I already knew it, but I had to relearn it the hard way this week.
