You have to drop down to JavaScript at some point, though in practice you would not write this much JavaScript mixed with Ruby in an app. The joy of using Opal is having the JavaScript wrapped away in a module, letting you use pure Ruby for your app. The author used a lot of JavaScript here, likely for teaching purposes, but he could instead have used pure Ruby to interface with canvas using opal-browser. https://github.com/opal/opal-browser/blob/master/opal/browse... |
