Function for a calendar formation in JavaScript

Let's wrap the calendar formation code in a function:

function draw(body, year, month) {
	let arr = range(getLastDay(year, month));
	
	let firstWeekDay = getFirstWeekDay(year, month);
	let lastWeekDay  = getLastWeekDay(year, month);
	
	let nums = chunk(normalize(arr, firstWeekDay, 6 - lastWeekDay), 7);
	createTable(body, nums)
}

In this case, we will be able to draw the calendar like this:

let date  = new Date();
let year  = date.getFullYear();
let month = date.getMonth();

draw(body, year, month)

Do as described.
