Benchmark: fizzBuzzTes - MeasureThat.net

Tests:

fizz1
var fizzBuzz = n => [...Array(n)].reduce((acum, value, index) => { const currentNum = index + 1; let num = currentNum; if (currentNum % 5 == 0) num = currentNum % 3 == 0 ? "FizzBuzz" : "Buzz"; if (currentNum % 3 == 0 && num !== "FizzBuzz") num = "Fizz"; acum.push(num.toString()); return acum; }, []);
fizz2
var fizzBuzz = function(n) { let arr = []; for (let i = 1; i <= n; i++) { if (i % 3 === 0 && i % 5 !== 0) { arr.push('Fizz'); } else if (i % 5 === 0 && i % 3 !== 0) { arr.push('Buzz'); } else if ((i % 3 === 0) && (i % 5 === 0)) { arr.push('FizzBuzz'); } else { arr.push(''+i+''); } } return arr; };

This benchmark tests the performance of two different approaches to solving the FizzBuzz problem in JavaScript.

**What is FizzBuzz?**

FizzBuzz is a classic programming challenge where you write a program that prints numbers from 1 to a given number (n). But, for multiples of 3, it should print "Fizz" instead of the number, for multiples of 5, it should print "Buzz", and for multiples of both 3 and 5, it should print "FizzBuzz".

**The Two Approaches:**

* **Test Case "fizz1":** This approach uses an arrow function (`n => ...`) with Array.prototype.reduce() to iterate through numbers from 1 to n. It creates an array and modifies it within the reduce loop by adding either the number itself or one of the FizzBuzz strings depending on divisibility rules.

* **Test Case "fizz2":** This approach uses a traditional function (`function fizzBuzz(n) {...}`) with a for loop.  It also iterates through numbers from 1 to n and builds an array by appending either the number itself or one of the FizzBuzz strings based on divisibility rules.

**Pros and Cons:**

* **fizz1 (Arrow Function, Reduce):**
    * **Pros:** Often considered more concise and readable for modern JavaScript developers. `reduce()` can be efficient for array manipulation.
    * **Cons:**  Might be less familiar to developers who are new to functional programming concepts or arrow functions. 
* **fizz2 (Traditional Function, For Loop):**
    * **Pros:** More traditional and widely understood approach. 
    * **Cons:** Can sometimes be considered less concise than modern JavaScript techniques.

**Other Considerations:**

* **Performance:** The benchmark results show that both approaches perform very similarly in this case.  There might be slight variations depending on the specific JavaScript engine and execution environment.

* **Alternatives:**
    * Using a `while` loop instead of a `for` loop wouldn't significantly change the performance.
    * You could use a library like Lodash for array manipulation, but it would likely add unnecessary overhead for this simple task.
