Vanilla JS application to find first N primes to show performance profiling
Use code snippets
Tags:
0-profile-method-call- initial unoptimized application. Try finding 1000 primes, should take about 8 seconds.1-removed-try-catch- removed first bottleneck, should take less than 5 seconds.2-reuse-primes- reusing previously found primes, makes finding 10k primes very fast.
The next two steps require running static server in order to load the web worker script.
3-web-worker- moved primes computation to a web worker.4-paint-profile- profile paint of expensive CSS property (box-shadow in index.html)
