This repo is just a proof of concept of using benchmark.js to measure the performance of different solutions to a same problem. We want to use it to create a kata challenge in our organization and let our program get the winner.
To add a new solution, you just have to create a node file with your name inside the folder functions. That JS file should be like:
module.exports = (misteryMessage) => {
//...your code goes here...
}To run a test function created in a standalone way, you can use index.js:
node index.js [functionName]i.e.
node index.js test-function-2022With this command, you'll run the file functions/test-function-2022.js
To run the benchmarker, once all the solutions are added to the folder, just run:
node benchmark.jsWith this command, you will run the benchmark for all the solutions inside the functions folder (one per file).
And you'll get stats and standings like:
@MacBoo ➜ benchmark node index.js
betisman x 101,306 ops/sec ±0.51% (94 runs sampled)
cesar x 1,002,139 ops/sec ±2.42% (92 runs sampled)
matteo x 8,099 ops/sec ±0.50% (95 runs sampled)
Fastest is cesar

└─────────┴───────────────┴─────────────┴─────────────────────┴──────────────┴─────────────────┴─────────────────────┘We have also implemented a traditional stopwatch benchmark just for fun and comparison, it can be run this way:
node traditional.jsWith this command, you will run the benchmark for all the solutions inside the functions folder (one per file).
And you'll get stats and standings like:
@MacBoo ➜ benchmark node index.js
testing betisman
testing cesar
testing matteo
Fastest is cesar
