💀 Dweetegem Hero #helldivers #strategem as a Dweet

I love the new Helldivers 2 game and made a Dweet-sized version of Strategem Hero.

a="⬅⬆➡⬇"
t?c.width=99:n=b=0
x.fillText((s=[...Object.keys(this)[n]].map(v=>a[v.charCodeAt()%4]).join``).substr(b),1,9)
onkeyup=e=>a[(e.keyCode-5)%4]==s[b]&&++b>=s.length&&(b=0,n++)

🤏 Dweet/Dwitter/Tiny Code/Code Golf Tips

A collection of tips when writing tinycode or dweets. It's getting hard for me to find the dweets that have neat tricks. I'll add more as I find more.

👉 Tip 1: `Math.floor` equivalents: `value|0`, `value>>0`, and `~~(value)`

For example when rounding down a value multiplied by Math.random, you can add |0.

Example getting a random integer from 0 to 254 (inclusive):

🏯💳 Dungeon Generator on a business card #bookmarklet

I saw this here: https://gist.github.com/munificent/b1bcd969063da3e6c298be070a22b604

But it was in C so I converted it into JavaScript. First I used this tool: https://www.codeconvert.ai/c-to-javascript-converter

And then I had to make a few tweaks to get it to display a to the screen.

Run it in your Address bar (802b bookmarklet)

👨‍💻 Three Implementations of `lodash` `_.uniq`

I was writing tiny code and attempted to get all unique values of an array.

I totally forgot the best implementation, but I thought my first 2 implementations use some interesting code golfing techniques.

The html file demonstrates its uses on an array of primitive values.
