It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips...

Yesterday, I finally nailed the technique for breast stroke at my swimming lessons. It was also the first time that I pretty much did laps non-stop.
For seasoned swimmers, probably not a big deal, but as a kid who did not learn this properly, it took a while to get it right as an adult.
I've always liked regular expressions, but due to my tendency in the past to focus on what I needed for tasks primarily, I never fully grasped look-ahead or look-behind. During this week I saw the simple thing I overlooked and saw how much it potentially opened up for me in the future.
I learned a thing or two (and I'm still studying this) about XorShift RNG, manily an algorithm called XorWow, by George Marsaglia. Their article can be found here.
It's a pretty interesting and uber fast algorithm for generating random numbers
This week, I learnt Angular testing and coverage reports. Seeing a coverage of 86% made me happy even though I know that won't prevent my code from breaking. It's a cool number to welcome me to Javascript testing :)
Learned how to wire up Firebase auth/db, netlify functions, and stripe payments. My brain is full.
Nice!
Managing client side state is hard. But a lot of times it worth the efforts
Also I learned a hacky way to stop page janking while image loading even if you don't know images height.
Sounds like it would make for a great post on DEV! 😎
Yeah, I'm procrastinating it from a few days. But I will let you know once completed.
GRAPH QL! (Well, I kinda knew it, but this week I actually buckled down to learn it and Apollo). GraphiQL in the browser made me happy.
Setting up a CSP for headers security isn't just a pain on its own, but even more so via Lambda@edge
