JS enter three integers a, B and C, and sort them from large to small (two methods)

            var a = Number(prompt(" Please enter an integer "));
			var b = Number(prompt(" Please enter an integer "));
			var c = Number(prompt(" Please enter an integer "));
			if (a > b && a > c) {
				if (b > c) {
					document.write(a + "," + b + "," + c);
				} else {
					document.write(a + "," + c + "," + b);
				}
			} else if (b > a && b > c) {
				if (a > c) {
					document.write(b + "," + a + "," + c);
				} else {
					document.write(b + "," + c + "," + a);
				}

			} else {
				if (a > b)
					document.write(c + "," + a + "," + b);
				else {
					document.write(c + "," + b + "," + a);
				}
			}

            var a = prompt(" Input a");
			var b = prompt(" Input b");
			var c = prompt(" Input c");
			var max = parseInt(a);


			if (b > a && b > c) {
				max = parseInt(b);
			}
			if (c > a && c > b) {
				max = parseInt(c);
			}

			var min = parseInt(a);
			if (b < a && b < c) {
				min = parseInt(b);
			}
			if (c < a && c < b) {
				min = parseInt(c);
			}
			var middle = (parseInt(a) + parseInt(b) + parseInt(c)) - (parseInt(max) + parseInt(min));
			document.write(max + "," + middle + "," + min);
