Without running the following code, try to determine:

let a = 1;
let b = 'bongos';
let c = true;
a = b;
b = c;
c = a;

• What is a?

a is 'bongos'

• What is b?

b is 'true'

• What is c?

c is 'bongos'

Output a console log The sum of 5 and 10 is 15 where the values for 5 and 10 are saved to variables, and where 15 comes from those variables being summed.

const num1 = 5;
const num2 = 10;

How can we make num3 equal to the sum of num1 and num2?

// your solution here
let num3 = num1 + num2;

Use variables num1, num2 and num3 to fill in the console.log() to complete the sentence:

The sum of 5 and 10 is 15

// your solution here 
console.log(num1 +" + "+ num2 +" = "+ num3);

By just looking at the following expressions, determine in your mind whether or not each will evaluate to true or false

a) 999 > 999
b) 999 === 999 
c) 999 !== 999
d) -5 >= -4
e) 100 <= -100
f) 20 + 5 < 5 
g) 81 / 9 === 9
h) 9 !== 8 + 1

Write true or false based on the list above

a) false
b) true 
c) false	
d) false 
e) false 
f) false 
g) true
h) false

1. Creat a variable called bill and assign it to 10.25 + 3.99 + 7.15 (let JavaScript do the calculation)
2. Create a vairable called tip and assign it to multiplying bill by 15% tip rate.
3. Add the bill and tip together and store it into a variable called total.
4. Print the total to the JavaScript console

Write your javascript solution below

// your answer here
let bill = 10.25 + 3.99 + 7.15;
let tip = bill * 0.15;
let total = bill + tip;

console.log("Total = "+ total);

Use the adjective variables below to fill in the blanks and complete the following message.
"Success is no accident. It is _________, _________, _________, _________, _________ and most of all, _________ of what you are doing or learning to do."

1. Declare a Quotes variable
2. Use the adjective1, adjective2, adjective3, adjective4 adjective5 and adjective6 variables to set the Quotes variable to the message: "Success is no accident. It is Hard Work, Perseverance, Learning, Studying, Sacrifice and most of all, Love of what you are doing or learning to do."

var adjective1 = "Hard Work";
var adjective2 = "Perseverance";
var adjective3 = "Learning";
var adjective4 = "Studying";
var adjective5 = "Sacrifice";
var adjective6 = "Love";

Assign the resulting string to a variable called Quotes

Write your javascript solution below

// your answer here
var quotes = console.log("Success is no accident. It is "+adjective1+", "
						+adjective2+", "+adjective3+", "
                        +adjective4+", "+adjective5+" and most of all, " 
                        +adjective6+" of what you are doing or learning to do.");

Here is a message:
"Hi, my name is Sara. I love cats. In my spare time, I like to watch movies"

1. Declare and assign values to three variables for each part of the sentence that changes (firstName, interest, and hobby)
2. Use your variables and string concatenation to create your own message and store it in an message variable
3. print your message to the JavaScript console.

Write your javascript solution below

// your answer here
var firstName = "Fatma";
var interest = "Art";
var hobby = "designing";

var message = "Hi, my name is "+firstName+". I love "+interest+" field. In my spare time, I like "+hobby+" User Interfaces";

console.log(message);

Write an if...else statement that:

1. prints "even" if the number is an even number
2. prints "odd" if the number is an odd number Hint: Use the % (modulo) operator to determine if a number is even or odd.

Write your javascript solution below

// your answer here
var num = 5;

if(num % 2 == 0){
	console.log(num+" Is Even");
}else if(num % 2 == 1){ //it'll give the same result if we removed if(num % 2 == 1),using the else alone
	console.log(num+" Is Odd");
}

Write a series of conditional statements that:

1. Prints "not a group" if musicians is less than or equal to 0
2. Prints "solo" if musicians is equal to 1
3. Prints "duet" if musicians is equal to 2
4. Prints "trio" if musicians is equal to 3
5. Prints "quartet" if musicians is equal to 4
6. Prints "this is a large group" if musicians is greater than 4 ex If musicians equals 3, then "trio" should be printed to the console.

Write your javascript solution below

// your answer here
var musicians = 3;
if(musicians <= 0){
	console.log("not a group");
}
else if(musicians == 1){
	console.log("Solo");
}
else if(musicians == 2){
	console.log("duet");
}
else if(musicians == 3){
	console.log("Trio");
}
else if(musicians == 4){
	console.log("Qurtet");
}
else if(musicians > 4){
	console.log("This is a large group!");
}

1. Research a loop so that your condition runs on every number from 0 to 100

// your answer here
var i;

for(i = 0;i<=100;i++){
  console.log(i);
}

2. Research a function so that your condition runs on every number from 0 to whatever number is passed into the function

// your answer here
var i;
var num = 9;

var iterations = function(num){
  
  for(i = 0;i<=num;i++){
    console.log(i);
  }
}

iterations(num);
