Fizz Buzz
- A function that takes in a parameter as number, let’s call it
num
- It will log out to the console every number from 1 to
num
- For each number, if the number is divisable by 3, it’ll output the word
Fizz
instead of the number. - For each number, if the number is divisable by 5, it’ll output the word
Buzz
instead of the number. - For each number, if the number is divisable by both 3 and 5, it’ll output the word
FizzBuzz
instead of the number.
Print all numbers from 1 till num
Using a for
loop
// print all numbers from 1 till `num`
for (i = 1; i <= num; i++) {
console.info(i)
}
Solution
function fizzbuzz (num) {
// print all numbers from 1 till `num`
for (i = 1; i <= num; i++) {
// if number divisible by both 3 and 5, print FizzBuzz
if ((i % 3 === 0) && (i % 5 === 0)) {
console.info(`FizzBuzz`)
}
// if number divisible by 3, print Fizz
else if (i % 3 === 0) {
console.info(`Fizz`)
}
// if number divisible by 5, print Buzz
else if (i % 5 === 0) {
console.info(`Buzz`)
}
// if not divisible by 3 or 5, just print the number
else {
console.info(i)
}
}
}
fizzbuzz(39)
We know that a number that is both divisibleby 3 and 5 is also divisible by 15. So
if ((i % 3 === 0) && (i % 5 === 0))
is the same as
if (i % 15 === 0)
