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.

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…

This week, the nodejs community had a big flame.

All was started by this blog post, which  tried to slap down node.js server because of its mono-thread nature. And node.js fight back knocking down the attacker. Let’see how.

So we are here again talking about Javascript. I have already wrote an article comparing a well known SmallTalk implementation to Javascript. If my ideas are right (at least a bit), you will see more and more javascript on the next months. In particular:

• JavaScript is the Ajax programming languge for the rest of us
• Mobile Framework like PhoneGap and Appcelerator, are all about javascript at the top
• Javascript is evolved, and it is used server side by projects like node.js

Phase3: Evolving to the next step

Coffee Script is a very instructive language. Look how CoffeeScript renders its code in JavaScript:it will avoid you a lot of mistakes.

And this bring us to a very sad rule: discipline in JavaScript is fundamental to avoid nasty bugs.
