This is pretty beefy for a cheatsheet. Can I get others to review? cc @szh @mackowski

I think this is good quality, but my main concern is the length. I wonder if we can make this more of a "cheat" and more concise.

[KadirArslan]

The reason it's so long is actually because of the code examples. I'm unsure too, but I thought code examples would be important for understanding.

[szh]

Agreed, it's not so long without the code samples. I think we have a way to make sections collapsible - maybe we can make the code samples collapsible so it's easier to read?

[szh]

I'm a fan. Great work @KadirArslan!

[KadirArslan]

Hey, thank you for the valuable comment @szh
I've updated the cheatsheet, made code examples collapsible.

Thanks, LGTM!
