Convert decimal number to any base and map the result to pre-defined dictionary.

// Convert decimal number to desired base and convert the result to it's respective alphabets from the dictionary.

function convertBaseFromDecimal(number, desiredBase) {
	var num = number;
	var rem = 0;
	var convertedNumber = [];

	// NOTE: Modify dictionary if desiredBase != 5
	var dict = {
		0 : "a",
		1 : "b",
		2 : "c",
		3 : "d",
		4 : "e",
	};
	var resultStr = "";

	while(num > 0) {
		rem = num % desiredBase;
		num = Math.floor(num / desiredBase);
		convertedNumber.push(rem);
	}

	for(var i = (convertedNumber.length - 1); i >= 0 ; i--) {
		resultStr += dict[convertedNumber[i]];
	}
	console.log(resultStr);
}

// Usage
function init() {
	convertBaseFromDecimal(3232, 5); //Output will be 'baaebc'
