[2.3.0] - 2021-04-06

Commit: cb740ed

Added

• Add timeout for executing polyfills.
• Add .name property to functions
• Add placeholder getter/setter functions on props
• Add announcement newsgroup address
• Use polyfills for Array functions.
• Support ‘null’ for ‘this’ value in strict mode.

Fixed

• Use Object.defineProperty instead of assignment.
• Fix attributes on Function.prototype
  • ‘typeof Function.prototype’ was reporting ‘object’, should be a ‘function’
• Handle ‘new’ calls on primitives.
• Catch calling date function on non-dates
• Catch invalid arguments on string’s localeCompare
• Called function should determine strict mode

Removed

• Remove enumerability from most global properties.

Changes

• New version of acorn
• In non-strict mode this needs to be boxed when calling a function.
• ‘window’ and ‘self’ are the only two enumerable properties on the global object.

[2.2.0] - 2020-02-18

Commit: d20cb5a

Added

• Partial support of JSON.stringify args.
  • Support pretty printing. Support array filtering. Do not support function replacers (this would need to be a polyfill).

Fixed

• Fix security hole in getOwnPropertyDescriptor
• Fix some JS Doc types
• Throw error where getter/setter not supported
  • There are several places where getters and setters are not handled correctly. Such as array’s .length. If a getter or setter is encountered in one of these places, throw an error, rather than performing invalid behaviour.

Removed

• Don’t set proto prop when exporting an object
  • proto is a magic property in most runtimes, but not in JS-Interpreter.
• Remove .isObject property
  • This property dates back to when primitives were also wrapped as objects and a way to distinguish objects and primitives was needed. Hopefully this change will also annoy @XmiliaH :)

Changes

• Split scopes into scope object and data object
  • Previously a scope object was a regular object with two extra properties tacked on: strict and parentScope. Issue #183 proved that sometimes one needs multiple scopes with different parentScope values. This PR creates a scope object with the above two properties, as well as a third property (‘.object’) that points to the regular object. This allows two scopes to have different parentScopes, while sharing the same object for variables.
  • Minor API change for advanced threading and serialization.

[2.1.0] - 2020-02-10

Commit: 28ba7f2

Added

• Non-constructable functions don’t have .prototype
  • Previously escape.prototype was set to undefined. Now it is not defined.
• Add self-interpreter demo.

Fixed

• Use iteration (not recursion) for polyfill steps.
• Revert "Remove unneeded error class"
  • Resovles #177
• Fix alert(true.toString())
  • Previously booleans and strings (but not numbers) would return ‘undefined’.
• Fix String and Number constructors with no arg.
  • Previously alert(Number()) -> NaN and alert(String()) -> ‘undefined’.
• Move constructor creation into createFunctionBase_
  • Fixes #175

Removed

• Remove ancient constants.
