My JSConf.US Presentation – Brendan Eich
@jashkenas was kind enough to let me join him for his JSConf.us session. Here is the slideshare link. I’ll comment on the individual slides below. Jeremy’s talk was entitled “CoffeeScript as a JS/next”, and I was interested in giving an update on Ecma TC39 Harmony progress, so when Jeremy and I met and caught up during the first day of JSConf, we quickly agreed on a joint session with about 15 min
The infernal semicolon – Brendan Eich
Most of the comments in this semicolons in JS exchange make me sad. The code in question: clearMenus() !isActive && $parent.toggleClass('open') relies on Automatic Semicolon Insertion (ASI) and so cannot be minified except by parsing fully (including ASI), observing the significance of the newline after clearMenus(), and inserting a semicolon when stripping that newline. Some argue that JSMin has
From ASM.JS to WebAssembly – Brendan Eich
tl;dr I’m burying the lede with context and catch-up material first, so impatient or already-clued-in readers should skip to below the videos for today’s big news. Or just read Luke Wagner‘s blog post right now. My Fluent 2015 “ECMAScript Harmony: Rise of the Compilers” talk given on April 21st: Jeremy Ashkenas picked up this ball and ran into the next field’s end zone two days later in Brooklyn:
Popularity – Brendan Eich
It seems (according to one guru, but coming from this source, it’s a left-handed compliment) that JavaScript is finally popular. To me, a nerd from a tender age, this is something between a curse and a joke. (See if you are in my camp: isn’t the green chick hotter?) Brendan Eich convinced his pointy-haired boss at Netscape that the Navigator browser should have its own scripting language, and that
New JavaScript Engine Module Owner – Brendan Eich
As you may know, I wrote JavaScript in ten days. JS was born under the shadow of Java, and in spite of support by marca and Bill Joy, JS in 1995 was essentially a one-man show. I had a bit of help, even at the start, that I’d like to acknowledge again. Ken Smith, a Netscape acquiree from Borland, ported JDK 1.0-era java.util.Date (we both just drafted off of the Java truck, per management orders;
Harmony Of My Dreams – Brendan Eich
Continuing in the vein of paren-free, I’d like to present a refreshed vision of JavaScript Harmony. This impressionist exercise is of course not canonical (not yet), but it’s not some random, creepy fanfic either. Something like this could actually happen, likelier and better if done with your help (more on how at the end). I’m blurring the boundaries between Ecma TC39’s current consensus-Harmony,
Proxy Inception – Brendan Eich
(Mobile/No-Flash version) These are based directly on the excellent work of Mark Miller and Tom Van Cutsem, who developed the harmony:proxies proposal that is now approved for the next major iteration of the JavaScript standard (ECMA-262, probably edition 6 but we’ve learned the hard way not to number prematurely — anyway, approved for “ECMAScript Harmony” [my original Harmony-coining post]).
