JavaScript: How to do a FizzBuzz programming task?

console log output of FizzBuzz program written in JavaScript

FizzBuzz programming task is a general interview question where the candidate need to write a program that prints either Fizz or Buzz or FizzBuzz along with the number.

For example, if you have a range of numbers from 0 until 100 that prints,

• Fizz if the number is a multiple of 3
• Buzz if the number is a multiple of 5
• FizzBuzz if the number is a multiple of 15 or a multiple of both 3 and 5

Below is the code on how you can do it in JavaScript programming language,

// FizzBuzz challenge
for (var i = 0; i <= 100; i++) {
  if (i % 15 === 0) {
    console.log("FizzBuzz", i)
  } else if (i % 5 === 0) {
    console.log("Buzz", i)
  } else if (i % 3 === 0) {
    console.log("Fizz", i)
  }
}

In the above code,

• for loop iterates by 1 and the loop starts with i 0 and ends when the value of i is 100.
• if expression returns a value either true or false if the number value in i is a multiple or not.
• console.log is a method for sending log output to the web console.
