Conditions
Without running the following code, try to determine:
let a = 1;
let b = 'bongos';
let c = true;
a = b;
b = c;
c = a;
```'bongos'
### Your solution here:
1. What is `a`?
a is ...
2. What is `b`?
b is ...
3. What is `c`?
c is ...
## 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("please" + " " +"squeeze" + " " + "the" + " " + "cheese")
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 ofnum1
andnum2
?
// your solution here
let num1 = 5;
let num2 = 10;
let num3 = num1 + num2
consol.log(num1 + "+" + num2 "=" + num3)
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
```js
console.log()
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
orfalse
based 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 a = 15;
if ( a % 3 === 0 && a % 5 ===0 ) {
console.log("buzz");
}
else if ( a % 5 === 0 ) {
console.log("fizz");
}
else if ( a % 3 === 0 ) {
console.log("FizzBuzz");
}
else {
console.log("a");
}
}
- 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
// your answer here
