Given an input, return the least change possible

coin_machine.js

const denomizations = [ .01, .05, .1, .25, .5, 1.0 ];
const input = .75;

function returnLeastChange(input = 0, change = {}, denomizations = []){
	let pointer = 0;
	const toReturn = {};
	let newInput = input;
	while(pointer < denomizations.length - 1){
		const x = denomizations[pointer];
		if(x <= newInput ){
			toReturn[x] = Math.floor(newInput/x);
			newInput = newInput % x;

		}
		pointer += 1;

	}
	return toReturn;
}

console.log(
	returnLeastChange(input, {}, denomizations.reverse(0))
)
