vanilla-primes

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)

If you need angular version of this application, see bahmutov/primes.
