Brendan Eich on ECMA TC39, and Google Dash
The creator of JavaScript talks about the future of JavaScript, how the ECMA standards committee works, and what he thinks about Google's forthcoming 'Dash' language which Google may be pitting directly against JavaScript. You can watch his talk in a video or just read his fine summary.
Critics call foul as Google takes aim at JavaScript with Dart
JavaScript is Not Web Assembly A common theme recently has been that JavaScript is the 'x86 of the Web'. That is, JS is a common base language others can compile too and then 'run anywhere'. But Isaac Schlueter doesn't think the comparison makes sense.

Why ++[[]][+[]]+[+[]] evaluates to '10' in JavaScript - Redux Remember "Why Does ++[[]][+[]]+[+[]] == 10 in JavaScript?" from last week. It was a popular item but JavaScript Weekly reader Tim Down found the answer to be particular accurate so he's written his own write up.

Stylus: An Expressive CSS Markup Language for Node.js Stylus is an attempt at creating another expressive language that can be converted to CSS (a la Sass). It's quite attractive and has Node.js as its focus (the compiler is written in Node.js).
