We have overhauled (entirely) the JavaScript support in odin, replacing an earlier attempt at this. The new approach uses our new TypeScript packages for working with ODE (odin-js) and discrete-time (dust-js) models, and power our new web interface to odin (see the wodin blog for more information on this).
Over the coming months, we plan to port some of the core sequential Monte Carlo algorithms (particle filtering and particle MCMC) to dust-js and enable use of these models on the web. We will also create some tutorials to get going with the models.
