Nightbot custom commands

This is an incomplete list of Nightbot commands I use on my Twitch channel to facilitate the teaching of webdesign. Many commands only generate links to specific sites, but some also offer advanced functionality, such as RNG. You should probably adjust the code, if you'd like to use them.

Random Number

Command: !random
Description: Generate a random number between 1 and 100, or a specific interval
Usage: !random, !random 1 10 or !random 5 20

$(eval if ($(1) && $(2)) {
	Math.floor(Math.random() * ($(2) - $(1) + 1) + $(1));
} else {
	Math.floor((Math.random() * 100) + 1);
})

Chance

Command: !chance
Description: Calculate a percentage
Usage: !chance 1 in 32

$(eval if ('$(1)' !== 'null' && '$(3)' !== 'null') {
	let n = 100 * parseInt('$(1)') / parseInt('$(3)'); 
	if (n % 1 === 0) {
		(n).toString() + '%'
	} else {
		(n).toFixed(2).toString() + '%' 
	}
} else { 
	'Usage: !chance [number] in [number], eg: !chance 1 in 5' 
})
