Activity Assignment

Without running the following code, try to determine:

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

a = b;
b = c;
c = a;

Your solution here:

1. What is a?

a is ...

2. What is b?

b is ...

3. What is c?

c is ...

Activity Concatenation

Use the + operator to concatenate these strings together within a console.log(): "Please", "squeeze", "the", "cheese". Make sure there are spaces in-between each word.

const firstWord = "Please";
const secondWord = "squeeze";
const thirdWord = "the";
const fourthWord = "cheese";

Result should be:

"Please squeeze the cheese"

Your solution here:

4. Fill in the console.log()?

console.log()

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;

Your solution here:

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

// your solution here

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

The sum of 5 and 10 is 15

console.log()

Activity Comparisons

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

Your solution here:

7. Write true or false based on the list above

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

Activity Conditionals

Declare a variable equal to a number 0 to 100

Write a conditional statement that...

• If it is a multiple of 3, print “Fizz” instead of the number.
• If it is a multiple of 5, print “Buzz” instead of the number.
• If it is a multiple of both 3 and 5, print “FizzBuzz” instead of the number.
• Otherwise, print the number

Your solution here:

8. Write your javascript solution below

BONUS

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

// your answer here

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

// your answer here
