Deno Vs. Bun Vs. Node.js: A Speed Comparison

Following our recent deep dive into the feature sets of JavaScript runtimes, I decided to put them to the test in terms of raw performance. I created a new benchmarking tool called jsrbench to provide a clearer picture of the performance of Deno, Bun, and Node.js under equivalent conditions. I also use another of my tools called primer to compare performance of prime number calculation using different approaches.
