fizzbuzz

#javascript #programming #beginners #interview

Write a function that returns the string representation of all numbers from 1 to n based on the following rules:

• If it's a multiple of 3, represent it as "fizz".
• If it's a multiple of 5, represent it as "buzz".
• If it's a multiple of both 3 and 5, represent it as "fizzbuzz".
• If it's neither, just return the number itself.

Example

function fizzBuzz(num){

}

input:15

output:'12fizz4buzzfizz78fizzbuzz11fizz1314fizzbuzz'.

Solution

function fizzBuzz(num) {
  let i = 1;
  let result = "";
  while (i <= num) {
    if (i % 15 === 0) {
      result += "fizzbuzz";
    } else if (i % 3 === 0) {
      result += "fizz";
    } else if (i % 5 === 0) {
      result += "buzz";
    } else {
      result += i;
    }
    i++;
  }
  return result;
}

const result = fizzBuzz(15)
console.log(result); // '12fizz4buzzfizz78fizzbuzz11fizz1314fizzbuzz'
