A well know logical question that you may face in a tech interview is FizzBuzz Problem. The Problem statement is something like below:

Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”

A simple Javascript solution to this is given below:

for (var i = 0; i <= 100; i++) {
    if (i % 3 == 0 && i % 5 == 0) {
        console.log('FizzBuzz')
    } else if (i % 3 == 0) {
        console.log('Fizz')
    } else if (i % 5 == 0) {
        console.log('Buzz')
    } else {
        console.log(i)
    }
}

This question can be modified in several way, one of which is "if the number is multiple of 3 or 5 print Buzz else Fizz". Write a solution in comment for this one.

Fun fact: The FizzBuzz problem is discussed in StackOverflow's 2019 Annual survey
