TypeScript: defining a top-level function
I use Lift as a web framework. Lift allows to generate JavaScript code and than to execute it on the page. I needed to execute a JavaScript function from that generated code. Since I use TypeScript for frontend development, I faced a problem here: How to create a global scoped function? Something like: window.myFunction = function(){ // … } Fortunately, I found a trick.

Scala.js and unidirectional data flow 2
Last time we talked about using Monix as a tool of creating unidirectional data flow in Scala.js applications. The tiny Dispatcher class was made for that purpose. We considered the Counter example, which demonstrated all the power of this approach. Today I intend to widen our horizons and to consider another example: more complex one: which will demonstrate not only usage of the Dispatcher but also usage of Sortable.js with React. But before that I want to add some new methods to the Dispatcher class. Here is the full code of the Dispatcher class: import monix.execution.Ack import monix.execution.Ack.Continue import monix.reactive.{Observable,
