As a mid-life greabeard that started my career on Z/OS / MVS writing JCL and running COBOL and SAS jobs, I like JavaScript. It doesn't have the obtuseness of C, the ultra-strict type-checking of Pascal, the verbosity of COBOL, class chaos of Java, the mind-bending notation of PostScript, nor the escapee from the loony bin mentality of SQL

To understand Angular 4, after the “Hero” tutorial you should start from the Template syntax.
We highlighted some statement in red below:
Data direction Syntax Type One-way from data source to view target \{\{expression\}\} [target]="expression" bind-target="expression" Interpolation Property Attribute Class Style One-way from view target to data source (target)="statement" on-target="statement" Event Two-way [(target)]="expression" bindon-target="expression" Two-way Binding types other than interpolation have a target name to the left of the equal sign, either surrounded by punctuation (
[],()) or preceded by a prefix (bind-,on-,bindon-).The target name is the name of a property. It may look like the name of an attribute but it never is. To appreciate the difference, you must develop a new way to think about template HTML.

Today I took a light rail with my son, to bring him to school. That tram is 90 years old. It has been maintained for 90 years. Milan city sold some of them to San Francisco too.

I have just read this insightful statement on this blog article about congitive load in Javascript
jQuery is undoubtedly useful when dealing with browser quirks, but once an application grows over a few thousand lines of code, unstructured jQuery code simply becomes too difficult to maintain, and you start needing the discipline of a framework to organize code. But when you're at tens of thousands of lines of code, you start to run out of entity types to CRUD, and your application growth starts to build on top of existing concepts. This is when you need the mental shift from being a library consumer to being a reusable component author,
This clever guy is the creator of Mithril, a very small, well crafted javascript library a friend of mine pointed to (via github…):

So Dart Sith has just launched his first DeathStar, my young JavaScript fellow: a site devoted to the Dart language
Because I am a very old Jedi (1974, before ever the first WtartWars trilogy showdown) I had to rest a bit before talking about it, so the news is 4-days old I know. I needed to think, reflect and write down: but now I am ready, Read on…

Old web site requires sometimes to show a big “Loading…” gif in the front of the page. It is not trivial to do it, especially if you have already plenty of jQuery forms developed, with complex form submission, and half the site in an ajax form.

Cappuccino è un progetto interessante, anche se molto particolare.
Cappuccino is an open source framework that makes it easy to build desktop-caliber applications that run in a web browser. Cappuccino is built on top of standard web technologies like JavaScript, and it implements most of the familiar APIs from GNUstep and Apple's Cocoa frameworks.
With Cappuccino, you don't need to know HTML. You'll never write a line of CSS. You don't ever have interact with DOM. We only ask developers to learn one technology, Objective-J, and one set of APIs. Plus, these technologies are implementations of well known and well understood existing ones. Developers can leverage decades of collective experience to really accelerate the pace of building rich web applications.
Tra i bonus di Cappuccino c'è la possibilità di programmarlo come se si stesse programmando in Objective-C ed in particolare in Cocoa. Può rappresentare un ottimo investimento se avete un background in XCode. L'interfaccia e le librerie constano in circa 10MB di codice compresso: non esattamente una passeggiata.Una delle applicazioni più complicate è http://280slides.com/ che però a tempi di caricamento abbastanza alti.
