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
- What is
b
?
b is ... true
- What is
c
?
c is ... bongos
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"
- 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
?
let num1 = 5
let num2 = 10
num3 = num1 + num2
- Use variables
num1
,num2
andnum3
to fill in theconsole.log()
to complete the sentence:
The sum of 5 and 10 is 15
let num1 = 5
let num2 = 10
let num3 = num1 + num2
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
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("fizzbuzz");
}
else if ( a % 3 === 0 ) {
console.log("fizz");
}
else if ( a % 5 === 0 ) {
console.log("buzz");
}
else {
console.log("a");
}
- Research a loop so that your condition runs on every number from 0 to 100
1)
do {
alert (d);
d++;}
while (d <= 100);
100
2)
for (let s = 0; s <= 100; ++s)
{alert(s);}
alert (s);
3)
let t = 0;
while (t<=100) {
alert(t);
t++;
}
- Research a function so that your condition runs on every number from 0 to whatever number is passed into the function
