Interesting
As we announced last month, Project Spartan will be the new browser across all Windows 10 devices, from phones to tablets, PCs and beyond. You'll hear about the new browser's features in the coming months but in this post, we want to tell you more about what motivated us to build a new rendering ...

Immutable.js - Immutable Data Collections http://ow.ly/DECsw
Immutable Data Collections. Converting to v3 from v2? Check out the upgrade guide. Immutable data cannot be changed once created, leading to much simpler application development, no defensive copying, and enabling advanced memoization techniques.

It is. :(  The linked article about gender color is also fascinating: http://www.smithsonianmag.com/arts-culture/when-did-girls-start-wearing-pink-1370097/?c=y%3Fno-ist

I love that image. It captures a lot about being a parent.

Here's the original for anyone out there who likes it as much as I do: http://www.deviantart.com/art/Be-Careful-160786906

As always some nice incremental improvements. Previously, one of the only things you needed to annotate was constructors, with ES6 classes this isn't needed and you still get proper checks. The new type inference is showing some good promise, fixing many outstanding bugs. The next few weeks, I also have high hopes for.
 
Closure Compiler v20141023 released!
https://github.com/google/closure-compiler/wiki/Releases

Changes:
* Add a warning for mistyping namespaces as Object. (See https://github.com/google/closure-compiler/wiki/A-word-about-the-type-Object for more explanation)
* New JS Conformance check: ban Closure-style top-level declarations from having implicitly public visibility.
* Migrated several lint checks into the compiler
* Default visibility levels in @fileoverview is now supported.
* File level @package no longer applies to goog.provide default namespaces
* Add a warning for misuse of goog.provides/goog.requires
* Fixes for goog.module rewriting
* Fix goog.defineClass when extending a generic class
* function(...[string]) can now be written as function(...string)
* "&&" and "||" are now allowed in @define default value expressions
* New type inference fixes:
  - Made nullable dereference checks suppressible in new type inference
  - Understand primitive unboxing
* A few fixes to ES6 transpilation of generators, spread operators, and synthesized class constructors, as well as updates to the module syntax tracking the spec.
