Simulating Sand: Building Interactivity With WebAssembly | JSConf EU 2019

“Falling sand games” were a beloved childhood curiosity, but when I
set out to write my own in Javascript, performance got in the way
of the scale and granularity I wanted. Could WebAssembly be the
tool to build the sand simulation of my dreams, or is it still just
for blog posts? I’ll share with you the history and beauty of
falling sand games, what I learned building mine to leverage the
power of modern browsers, and show you how WebAssembly can
cooperate productively with the JS ecosystem to enable awesome web
experiences.
