Unit V - Lesson 4

6.4.1. if-else statement

// write your code below this line
if((year % 4 === 0 && year % 100 !==0) || year % 400 === 0){
	var nDays = 366;
}else{
	var nDays = 365;
}

6.4.2. switch-case statement

// write your code below this line

switch (colorCode) {
	case 'V':
		colorName='Violet';
		break;
	case 'I':
		colorName='Indigo';
		break;
	case 'B':
		colorName='Blue';
		break;
	case 'G':
		colorName='Green';
		break;
	case 'Y':
		colorName='Yellow';
		break;
	case 'O':
		colorName='Orange';
		break;
	case 'R':
		colorName='Red'
		break;
}

6.5.1. for loop

function computeSeries(){
	let seriesN = 0;
	for(let i = 1; i<=N; i++){
		seriesN += i ** 2;
	}
	window.seriesN = seriesN;
}
computeSeries();

6.5.2. for loop - continue statement

let sum = 0;
for(let i = 1; i<=N; i++){
	let square = i * i;
	if(square % 10 === 0){
		continue;
	}
	sum+=square;
}
seriesN = sum;

6.5.3. while loop

let a = 1, b = 1;
if (N === 1 || N === 2){
	fibN = 1;
}else{
	let count = 2;
	while(count < N){
		fibN = a + b;
		a = b;
		b = fibN;
		count ++
	}
}
fibN;
