Diff between event-driven and FRP.

gistfile1.js

// event driven
loadArticle(function (article) {
  myTextField.text = article.title;
  if (article.title == "toto")
    alert("Toto arrived");
});

// FRP
var article = loadArticle();
article.whenAnyValue('title').bindTo(myTextField.text);

article.where(function (theArticle) {
  return article.title == "toto";
}).subscribe(function (theArticle) {
  alert("Toto arrived !");
});
