> Thanks! So is PropertyMapHashTable for properties that have been defined by the user, or is it not that simple?
> Apologies. Basically, does the implementation of object property access in the JIT codebase also use strings which have been made unique identifiers in the same way as in the runtime stack? (i.e. can they be assumed equal iff they have the same address).
Yes -- typically, though, if the JIT needs to do a hash lookup, it will pass an Identifier to a C++ helper function.
