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

After years of typing "npm run [script]", by habit, I just happened to stumble on this in vs code. Hover over the script name and click run. (I know, probably nothing new to everyone, but new to me :))


I think you can also add scripts to the sidebar in VS Code, which lists the scripts and lets you run them from there.


That's really cool too! I don't know how I missed that!


How to use lenses in f# to drasticaly simplify updating nested records


Which library did you use, aether?


I use fsharpplus because the aether website was down when I decided to try lenses:)


Sounds like it would make for a great post on DEV and/or your blog!


Never wrote a blog before but i might try


This week, I learned to rely on shopify apps the hard way. The client I work with lessened the hours on my timedoctor due to an unjustifiable amount of time implementing a requested feature rather than going through the apps on the app store.


This week, I learnt that you can stash one file instead of all files. I figured it was possible, but never really had a need to do it until this week.

git stash push -- path/to/your/file/your-file.extension

Interesting. The other day I learned that you can checkout a single file from another branch to the current branch you're working on.


Oh, man - third week of JS class, and since it's all new to me, the list of what I learned this week would take up too much space! :) Probably the most useful thing I learned this week was how arrays sort elements by converting them to strings then comparing their UTF-16 code unit values.


I learned how to use PHP Storm and OMG it's amazing!


I learned Jest! I feel safer now


I learned how to use RabbitMQ as the communications layer for my microservices.


This week I learned enough of the pygame python library to be dangerous. I am pretty excited to start making silly games again!


I learn manage server using moss.sh
