Conditions
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"
2. What is `b`?
b is true
3. What is `c`?
c is "bongos"
## 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.
```js
const firstWord = "Please";
const secondWord = "squeeze";
const thirdWord = "the";
const fourthWord = "cheese";
Result should be:
"Please squeeze the cheese"- Fill in the
console.log()?
console.log(firstWord + " " + secondWord + " " + thirdWord + " " + fourthWord)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
num3equal to the sum ofnum1andnum2?
// let num3 = num1 + num2;- Use variables
num1,num2andnum3to fill in theconsole.log()to complete the sentence:
The sum of 5 and 10 is 15
console.log("The sum of " + num1 + " and " + num2 + " is " + 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
trueorfalsebased on the list above
a) false
b) true
c) false
d) false
e) false
f) false
g) true
h) false
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
- Write your javascript solution below
// let fiz = 5;
// if (fiz % 3 === 0 && fiz % 5 === 0) {
// fiz = "FizzBuzz";
// }else if (fiz % 3 === 0){
// fiz = "Fizz";
// }else if ( fiz % 5 === 0) {
// fiz = "Buzz";
// }else {
// fiz = fiz;
// }- Research a loop so that your condition runs on every number from 0 to 100
// your answer here- Research a function so that your condition runs on every number from 0 to whatever number is passed into the function
/*
function check(num){
if (num % 3 === 0 && num % 5 === 0) {
num = "FizzBuzz";
return num;
}else if (num % 3 === 0){
num = "Fizz";
return num;
}else if ( num % 5 === 0) {
num = "Buzz";
return num;
}else {
return num;
}
}
