Allen discussed the future of ECMAScript at a TC39 meeting a couple of weeks ago. He discusses scaling TC39 to an organization that can properly standardize “this era’s canonical programming language”. Allen goes on to discuss specification internals.

Michael with a very early stage (stage 0) proposal to bring interfaces to JavaScript. Here’s a rough example of how the proposal looks like in its current state:

interface ISerializable {
  serialize;
  deserialize;
}
class SerialNumber implements ISerializable {
  constructor(raw) {
    this.raw = raw
  }
  [ISerializable.serialize]() {
    return this.raw
  }
  [ISerializable.deserialize](value) {
    return new SerialNumber(value)
  }
}

The WebKit team describes the development of an ES6 benchmark they’re dubbing ARES-6.

ARES-6 runs benchmarks multiple times to gather lots of data about how the browser starts up, warms up, and janks up.

Maxime guides you along the necessary steps to port a JavaScript library of the Conway’s game of life to WebAssembly.

Ire explains mimax(), and how we can code up succinct but powerful CSS grids with it, to maximize responsive fluidity.

Gyroscopes found on modern phones are powerful enough to pick up low-frequency information. Machine learning can augment the signals and even parse speech. On a related note, your accelerometer can be used to crack your passwords.

In February 2015, Daniel found and reported an XSS vulnerability in HackerOne, caused by React interpreting an improperly validated input as a React element. Corollary: avoid blanket JSON.parse calls and sanitize your inputs!

An XSS issue affected all Shopify stores that could be triggered via window.postMessage from any remote origin. The report demonstrated a clever bypass of the escaping code Shopify had in place to prevent code injection.

Turns out HTTP/2 push is, at this time, inconsistent between browsers. Jake with a detailed piece about the discrepancies that’s also littered with recommendations.

Let’s not automate everything away, urges Chip in a tribute to the benefits of occasional manual performance audits.
