Thomas Jensen tjconcept

If you wish to put the entire fee on your customer, remember that the customer must also pay the fee of collecting the fee itself.

r = 0.025 // (rate fee)
f = 0.25 // (flat fee)

O = 100 // original amount (the cost of some product)

Naive (wrong) approach:

I hereby claim:

I am tjconcept on github.
I am thomasjensen (https://keybase.io/thomasjensen) on keybase.
I have a public key whose fingerprint is CC4C DE2E 97F2 EEA0 5C3A C2AE 60BE 7EA0 1EB0 4B01

To claim this, I am signing this object:

	throw new Error('Missing expected function argument')
	}
	return Promise.all(Object.values(hash)).then((values) =>
	fn(
	Object.fromEntries(
	Object.keys(hash).map((key, idx) => [key, values[idx]])
	)
	)

	class Rejection {
	constructor(reason) {
	this.reason = reason
	}

	export default function using(...args) {
	const lastIdx = args.length - 1
	const fn = args[lastIdx]
	if (typeof fn !== 'function') {

	export default function using(...args) {
	const fn = args.at(-1)
	if (typeof fn !== 'function') {

	}
	if (args.length < 2) {
	throw new Error('At least two arguments must be passed')
