Introducing SIMD.js – Mozilla Hacks - the Web developer blog
SIMD stands for Single Instruction Multiple Data, and is the name for performing operations on multiple data elements together. For example, a SIMD add instruction can add multiple values, in parallel. SIMD is a very popular technique for accelerating computations in graphics, audio, codecs, physics simulation, cryptography, and many other domains. In addition to delivering performance, SIMD also

Nginx has big plans for JavaScript
The company plans to let you use JavaScript as an application language in its eponymous Web server Nginx (pronounced “engine xâ€) has become so popular as a Web server, with an estimated installed base of 140 million websites, that it now runs 38.8 percent of the top 1,000 websites as ranked by Alexa this spring, surpassing Microsoft and Apache servers. It also has attracted the attention of Canoni
Slimmer and faster JavaScript strings in Firefox
Since Brendan Eich wrote the first SpiderMonkey version in 1995, there have been many, many changes to its internal string representation. New string types like inline strings (more on this below) and ropes were added to save memory and improve performance, but the character representation never changed: string characters were always stored as a sequence of UTF-16 code units. The past two months I

JavaScript and V8 TurboFan Aug 3, 2014 5 min read #javascript #performance #v8 #web Recently, Google engineers landed a new optimizing JavaScript compiler for V8, codenamed TurboFan. As the name implies, this is supposed to further improve JavaScript execution speed, likely to be better than its predecessor, Crankshaft. While TurboFan is still in its early stage, that doesn’t mean we can’t take a

Collections for JavaScript
This package provides JavaScript implementations of common collections, with many useful features. These collections provide specialized alternatives to plain arrays and objects. They include the ability to observe all changes, have a common interface across every collection and work in both Node.js and the browser. Some data structures are better suited for specific problems. The collections pack
StrongLoop - Generators in Node.js: Common Misconceptions and Three Good Use Cases
Generators have been all the rage lately. Many Node developers (including myself!) are excited and intrigued about writing their asynchronous code like this: However, this is just one use case (although a clever one) of using generators. In this article, we will explore the strengths of using generators. There is a GitHub repository with the code samples we will go through that you can check out.

> Javascript has been a multi-billion dollar focus by several top-tier engineering companies for almost two decades.No, that's an exaggeration in time and dollars. JS was one full-time person, me, till fall 1996, then two. Growth after that was to about eight max, and less than the Java crew at Netscape, until Netscape folded on Java and laid off a bunch of people in late 1997. Call the Netscape i
Callbacks, Promises, Signals and Events | Blog | Miller Medeiros
Sometimes I get involved in discussions on twitter and Facebook related to development. This week I ended up sending a link to an old(ish) twitter thread explaining when to favor Promises/Callbacks and when to use Signals/Events for asynchronous operations. I think this topic deserves further explanation. Callbacks are commonly used when you have an asynchronous operation that should notify the ca
JavaScript gains support for SIMD
Update 2017-05-08: a proposal for SIMD.js has been rejected, in favor of providing similar functionality via WebAssembly. Recently, a new JavaScript feature has landed for the next Firefox Nightly: an API for SIMD (Single Instruction, Multiple Data). This blog post explains how the API works and how it fits into the JavaScript landscape. What is SIMD? SIMD is the ability of a CPU to apply an opera
