GNOME JavaScript/Spidermonkey bindings

News
====

- New JavaScript features! This version of GJS is based on SpiderMonkey 31, an
  upgrade from the previous ESR (Extended Support Release) of SpiderMonkey 24.
  Our plans are to continue upgrading to subsequent ESRs as maintainer
  availability allows. Here are the highlights of the new JavaScript features.
  For more information, look them up on MDN or devdocs.io.

  * New syntax
    + Spread operator in function calls: someFunction(arg1, arg2, ...iterableObj)
    + Generator functions: yield, function*, yield*
    + Binary and octal numeric literals: 0b10011100, 0o377
    + Function arguments without defaults can now come after those with
      defaults: function f(x=1, y) {}

  * New standard library module
    + Intl - Locale-sensitive formatting and string comparison

  * New APIs
    + Iterator protocol - any object implementing certain methods is an
      "iterator"
    + New Array functionality: fill(), find(), findIndex(), of()
    + New String functionality for working with Unicode: codePointAt(),
      fromCodePoint(), normalize()
    + New Array methods for correspondence with Object: entries(), keys()
    + ES6 Generator methods to replace the old Firefox-specific generator API:
      next(), throw()
    + forEach() methods for Map and Set, for correspondence with Array
    + A bunch of new Math functions: acosh(), asinh(), atanh(), cbrt(), clz32(),
      cosh(), expm1(), fround(), hypot(), log10(), log1p(), log2(), sign(),
      sinh(), tanh(), trunc()
    + Some constants to tell information about float support on the platform:
      Number.EPSILON, Number.MAX_SAFE_INTEGER, Number.MIN_SAFE_INTEGER
    + New Number.parseInt() and Number.parseFloat() which are now preferred over
      those in the global namespace
    + New Object.setPrototypeOf() which now is preferred over setting
      obj.prototype.__proto__
    + New locales and options extra arguments to all toLocaleString() and
      related methods
    + Misc new functionality: ArrayBuffer.isView(), Proxy.handler.isExtensible,
      Proxy.revocable()

  * New behaviour
    + -0 and +0 are now considered equal as Map keys and Set values
    + On typed arrays, numerical indexed properties ignore the prototype object:
      Int8Array.prototype[20] = 'foo'; (new Int8Array(32))[20] == 0

  * New non-standard Mozilla extensions
    + Array comprehensions
    + Generator comprehensions; both were originally proposed for ES6 but removed
