Upcoming Changes to the JavaScript Language

Google Tech Talks
November, 14 2007

ABSTRACT

After eight years of work in the standards committee, JavaScript will soon get an update. We present the highlights and rationales of the proposed changes to JavaScript.

The fourth edition of the ECMAScript (JavaScript) language represents a significant evolution of the third edition language, which was standardized in 1999. ES4 is compatible with ES3 and adds important facilities for programming in the large (classes, interfaces, namespaces, packages, program units, optional type annotations, and optional static type checking and verification), evolutionary programming and scripting, data structure construction, control abstraction (proper tail calls, iterators, and generators), and introspection. Improved support for regular expressions and Unicode, richer libraries, and proper block scoping are also added.

OO all the way.

If you can get the same improvement in ECMAScript as has already been achieved between PHP versions 4 and 5, then you have my blessings. Specifically, the availability of a Standard ECMAScript Library implemented in fast native code would be a TREMENDOUS IMPROVEMENT. Check out the Standard PHP Library (SPL) for an example.

Waldemar is an incredibly smart guy, his parents were electronic engineers from poland, and he was on the International Mathematical Olympiad team as a high school student, so he was incredibly good at math. In fact, he was a Putnam fellow in 1986 as well.

but php will be scalable in the future..believe me...

nontheless ppl still develpong website in php

[bytedildo]

yes, php will evolve, so will other mainstream languages, but I am not talking about languages here, I am talking about full development stacks built for special needs. Name one php framework for building web apps that can compete with grails. Php solutions (at the moment) don't scale very well in production environment. Twitter not long ago, had problems for choosing the wrong tecnology, I think it was php :)

[slier81]

what u think about open source project?

still stay the same?

u can see php will evolve to fully oop lang

[bytedildo]

it is more than just hype, it's a manifestation of finally something great!! You will see it in 5 years what I'm talking about.

[slier81]

u just got influce by current hype..

nothing more that that...

[ssokolow]

Yeah, but why? That's the important question. In my opinion, it can be summed up by paraphrasing a tongue-in-cheek response I ran across. "PHP has a design?"

I've done quite a bit of work in PHP and, in general, the biggest issue I have is that the standard library is a mish-mash of stuff and almost any task I perform requires code from the PHP manual comments because the library is incomplete. (eg. There's code for parsing URLs but not unparsing them. There's no way to compare GD pixmaps. etc)

HEY! check out our new band, we are up and coming :D

[bytedildo]

dude, php is so yesterday. Now it's all about groovy , ruby and python.
