JavaScript experiments by B.J.       Home
Optimized for PC with mouse (Windows 10 + Chrome or Firefox). May not work on mobile devices (iOS, Adroid + Safari, etc.).
OBS: Computationally demanding animations may benefit from 'hardware acceleration' (Chrome advanced settings). Pictures/photos are rendered best without!
Primes Explores the swiftness of JavaScript finding prime numbers, using Eratosthenes' sieve.
Viewer Photo display using JavaScript.
