Filling some Typescript gaps:

The longer you have been around, the more the landscape shifts.
We often learn just enough to move forward.
You might even study intently.
But then, you may have studied and learned a feature set that has since had more features published/released.

Looking at some tan-stack table code today ran into some typescript that was foreign to myself: link.

According to the typescript docs this is called optional-element-access, which lets you access both objects and arrays with strings and/or numbers.

Had a fun thought today around teaching others.

Curious to see if anyone violently disagrees. 🙂
Or violently agrees. Or has a more tempered reaction or adjacent take.
Feel free to post in the comments.

My hot take on learning/teaching things to set people up for success:

The key thing for you with learning typescript is to keep it as simple as possible.

Your challenge, If you choose to accept...
(mission impossible music)

This is going to be a weird assignment. For now a week long effort and we re-evaluate at the end of the week.

If you accomplishing one thing would be huge. I am just going to throw a ton of stuff at you and see where we end up. I will also probably be involved at some points working on stuff.

Terms

pick up time around 7am? (negotiable, also I might oversleep 😅)
we work from the home office (I will have it all clean)
when we go out for coffee or lunch I can buy.
end the day

In the immortal words of Rick and Morty:

Don't ... mess ... with ... time!!

Response: I will mess with time!, I will mess with time.

Disclaimer, all dates were run in macOs Chrome browser console. Your mileage may vary.

It started with a simple question I asked myself around dates.

Change your timezone on mac computer:
Useful when you are travelling to be in your home timezone.

Sourced from here: https://apple.stackexchange.com/a/117995/200795

sudo systemsetup -listtimezones

# copy the <timezone> you want to add
sudo systemsetup -settimezone <timezone>

note to self, is there a command line tool on homebrew to use instead?

find .  -type f | grep -v git | grep -v mov | xargs cat |  tr -c '[:alnum:]' '[\n*]' | sort | uniq -ci | sort -n

A fun way to read through a javascript project.

TLDR;

git log --reverse --merges | grep Pull and git log --merges --oneline.

Summary:

Your package. json file will tell the story of the dependencies in your project.
I wanted to find out when a certain dependency changed which caused a project structure change.

To achieve I setup a:

A terminal on the left running the log commands on the package.json file.

	function hhelp() {
	help $1 > /dev/null 2>&1 && echo "yes, help $1" \|\| echo "no, help $1" ;
	man $1 > /dev/null 2>&1 && echo "yes, man $1" \|\| echo "no, man $1";
	$1 --help > /dev/null 2>&1 && echo "yes, $1 --help" \|\| echo "no, $1 --help";
	$1 -h > /dev/null 2>&1 && echo "yes, $1 -h" \|\| echo "no, $1 -h";
	apropos $1 > /dev/null 2>&1 && echo "yes, apropos $1" \|\| echo "no, apropos $1";
	whatis $1 > /dev/null 2>&1 && echo "yes, whatis $1" \|\| echo "no, whatis $1";
	which $1 > /dev/null 2>&1 && echo "yes, which $1" \|\| echo "no, which $1";
	}
	# because sometimes it is hard to find the correct help function on command line.
