assemblyscript/examples/n-body

N-body system

An AssemblyScript example. This is actually a benchmark - visualizing it just so happened.

Instructions

First, install the development dependencies:

$> npm install

Now, to build assembly/index.ts to an untouched and an optimized .wasm including their respective .wat representations, run:

$> npm run asbuild

Afterwards, run npm run server to start a local server. Should also automatically launch a browser.

To run the benchmark:

$> npm run test [steps=1000000]
