- * In the original JS engine design, obj->slots pointed to a vector of length
- * JS_INITIAL_NSLOTS words if obj->map was shared with a prototype object,
- * else of length obj->map->nslots. With the advent of JS_GetReservedSlot,

- * of the minimum length slots vector in the case where map is shared cannot
- * be constant. This length starts at JS_INITIAL_NSLOTS, but may advance to
- * include all the reserved slots.
- *
- * Therefore slots must be self-describing. Rather than tag its low order bit
- * (a bit is all we need) to distinguish initial length from reserved length,
- * we do "the BSTR thing": over-allocate slots by one jsval, and store the
- * *net* length (counting usable slots, which have non-negative obj->slots[]
- * indices) in obj->slots[-1]. All code that sets obj->slots must be aware of
- * this hack -- you have been warned, and jsobj.c has been updated!
