Tests:
Array join
console.log( Array.apply(null, {length: 100}).map(function(val, index) { return (++index%3?'':'Fizz')+(index%5?'':'Buzz')||index; }).join('\n') );
Array map
console.log( Array.apply(null, {length: 100}).map(function(val, index) { index++; if (index % 15 == 0){return "FizzBuzz";} if (index % 3 == 0){return "Fizz";} if (index % 5 == 0){return "Buzz";} return index; }).join('\n') );
Fill function Map function
console.log( Array(100) .fill((x, div, label) => x % div ? "" : label) .map(function(func, idx) { return func(++idx, 3, "Fizz") + func(idx, 5, "Buzz") || idx }) .join('\n') );
early return minified
console.log( Array(100) .fill((z=>z%15==0?"FizzBuzz":z%3==0?"Fizz":z%5==0?"Buzz":z)) .map(((z,o)=>z(o+1))) .join('\n') );
Map arrow function
console.log( Array(100) .fill((x, div, label) => x % div ? "" : label) .map((func, idx) => func(++idx, 3, "Fizz") + func(idx, 5, "Buzz") || idx) .join('\n') );
Fill with function function
console.log( Array(100) .fill(function(x, div, label) { return x % div ? "" : label}) .map(function(func, idx) { return func(++idx, 3, "Fizz") + func(idx, 5, "Buzz") || idx }) .join('\n') );

Let's dive into the world of JavaScript microbenchmarks! **What is being tested?** MeasureThat.net is testing the performance of different ways to implement the Fizz Buzz algorithm, which prints numbers from 1 to 100, replacing multiples of 3 with "Fizz", multiples of 5 with "Buzz", and multiples of both with "FizzBuzz". The benchmark is comparing various approaches to create this sequence. **Options being compared:** The benchmark compares six different options: 1. **Array join**: Using the `join()` method to concatenate the numbers in an array. 2. **Array map**: Using the `map()` method to transform each number in an array into a string. 3. **Fill function Map function**: Creating an array with the Fizz Buzz algorithm using a fill function and then mapping over it. 4. **Early return minified**: Implementing the Fizz Buzz algorithm using early returns with a minimalized syntax. 5. **Map arrow function**: Using an arrow function to map over the numbers in an array. 6. **Fill with function function**: Creating an array with the Fizz Buzz algorithm using a fill function and then mapping over it, similar to option 3. **Pros and cons of each approach:** 1. **Array join**: Pros - simple and easy to understand, good for small arrays. Cons - can be slow for large arrays due to string concatenation. 2. **Array map**: Pros - efficient for large arrays, as it avoids the overhead of string concatenation. Cons - may require more memory to store the intermediate results. 3. **Fill function Map function**: Pros - similar to Array join in terms of simplicity and readability, but with the added efficiency of array mapping. Cons - still requires a bit more memory than just an array join. 4. **Early return minified**: Pros - minimalized syntax can lead to faster execution, especially for small arrays. Cons - may be harder to understand due to its concise nature. 5. **Map arrow function**: Pros - similar to Array map in terms of efficiency and readability. Cons - may require more advanced JavaScript knowledge to write effectively. 6. **Fill with function function**: Pros - similar to Fill function Map function, but with the added benefit of a clear separation between creating the array and mapping over it. Cons - still requires a bit more memory than just an array join. **Libraries used:** * None mentioned in the benchmark definition or test cases. **Special JS features/syntax:** None explicitly mentioned, but `arrow functions` are used in options 5 and 6. **Other considerations:** The benchmark likely considers factors such as: * Memory usage * Execution time * Code readability and maintainability In conclusion, MeasureThat.net's benchmark provides a valuable comparison of different approaches to implementing the Fizz Buzz algorithm in JavaScript. By considering various aspects of performance, memory usage, and code readability, developers can choose the most suitable approach for their specific use case.
