This is a simple JavaScript Fizz Buzz solution based on a Codecademy exercise. I refactored it down a few lines after seeing these implementations.
I wanted to post here and see what else I can learn from this basic exercise.
for (var i = 1; i <= 20; i++) {
var result = "";
if (i % 3 === 0) { result = "Fizz"; }
if (i % 5 === 0) { result += "Buzz"; }
console.log(result || i);
}
