Oh well, a rant against another one ... how lovely is this? Just trying to make your week end, right? I am talking about this misleading post with indeed 29530+ views and just 1 Favorited entry (right now) that must be the post author itself since I can't even check and click that red link ... anyway ... At the very beginning I thought that was a sarcastic post .. like, the opposite of reality, then I have realized it wasn't ... or was it? V8 is not server-class ? Define "server class programming language" first ... 'cause I have tried to search it in Google (with quotes) and result was like a single entry that indeed pointed to some Java stuff ... This argument is kinda boring in 2012, specially against a general purpose programming language as JS is, you don't say? I mean, doooooode, should I remind you the Java Applet joke early in the Web era? So it was fine for a server-class programming language to do client side stuff? Or it's just a matter of ...

Few days ago I was having beers with @aadsm and @sleistner and we were talking about languages and, of course, JavaScript too. That night I have realized there is a missing process, or better tool, that could open new doors for JavaScript world. The Runtime Nightmare The main difference between scripting languages and statically typed one is the inability to pre optimize or pre compile the code before it's actually executed. Engineers from different companies are trying on daily basis to perform this optimization at runtime, or better Just In Time, but believe me that's not easy task, specially with such highly dynamic language as JavaScript is. Even worst task is the tracing option: at runtime each reference is tracked and if its type does not change during its lifecycle, the code could be compiled as native one. The moment a type, an object structure, or a property changes, the tracer has to compile twice or split the optimizations up to N exponential changed performed in a...

Just a quick one about two technical reviews out of two I have recently done for @stoyanstefanov and @cjno for these completely different books: JavaScript Patterns and Test-Driven JavaScript Development . Right now these are both Top 10 Bestsellers and trust me: other JavaScript Jedis have been involved, you won't regret these lectures! ;-)

Io is a small, prototype-based programming language. The ideas in Io are mostly inspired by Smalltalk (all values are objects, all messages are dynamic), Self (prototype-based), NewtonScript (differential inheritance), Act1 (actors and futures for concurrency), LISP (code is a runtime inspectable/modifiable tree) and Lua (small, embeddable). This programming language is really interesting, starting from syntax, throw the entire guide . One of its primitive type is called List, and this is a summary of this type: A List is an array of references and supports all the standard array manipulation and enumeration methods. It seems that List is all we need when we think about an Array of elements ... so why couldn't we have something similar in JavaScript? // Io programming language List example // followed by my JavaScript List implementation a := List clone a = List.clone() a := list(33, "a") a = list(33, "a") a append("b") a.append("b") ==> ...
