LeetCode 412: FizzBuzz | Clean JavaScript Solution

In this video, I solve LeetCode 412: FizzBuzz using a simple for loop and conditional logic in JavaScript.

The FizzBuzz problem is a classic beginner coding challenge that checks your understanding of loops, conditionals, and string manipulation.

I walk through how to handle all three cases:

Multiples of 3 → “Fizz”

Multiples of 5 → “Buzz”

Multiples of both → “FizzBuzz”

This is a great starting point if you're new to coding interviews or JavaScript.

What You’ll Learn:
✅ Clean conditional logic using if/else
✅ Handling multiple divisibility checks
✅ How to build a result array in-place
✅ Time & space complexity breakdown
