Andreas Kling	542108421e	LibJS: Support "hello friends".length ... The above snippet is a MemberExpression that necessitates the implicit construction of a StringObject wrapper around a PrimitiveString. We then do a property lookup (a "get") on the StringObject, where we find the "length" property. This is pretty neat! :^)	2020-03-11 19:00:26 +01:00
Andreas Kling	386867da9f	LibJS: Add a convenience helper for visiting a JS::Value ... We only really care to visit values if they refer to a Cell, but it's nice to be able to say visit(some_value).	2020-03-09 22:19:06 +01:00
Andreas Kling	63e4b744ed	LibJS: Add a basic mark&sweep garbage collector :^) ... Objects can now be allocated via the interpreter's heap. Objects that are allocated in this way will need to be provably reachable from at least one of the known object graph roots. The roots are currently determined by Heap::collect_roots(). Anything that wants be collectable garbage should inherit from Cell, the fundamental atom of the GC heap. This is pretty neat! :^)	2020-03-08 19:23:58 +01:00
