itself seems a step back, but the primary aim is opening future optimization opportunities. The list of changes follows: - Property is changed to be an abstract type, which has type, flags, and a value. It does not have a name anymore and property pointers cannot be compressed. - Full (32 bit) ecma values can be property values. This allows using non-compressed pointers for ecma values in the future. - The property chain is not restricted to the same item anymore, it can contain hash maps, arrays in the future.
