···330330- Updated all array methods across builtins (push, pop, shift, unshift, slice, splice, etc.)
331331- **Result**: Reduced array reallocation overhead
332332333333+#### Sprint 1.3: Fast Path for Array Element Access
334334+- Added `[@inline]` to `get_array_el` and `set_array_el`
335335+- Fast path for Int values: direct Int32.to_int conversion
336336+- Fast path for integer Float values: direct int_of_float
337337+- Fallback to full to_int32 only for other types
338338+- **Result**: Eliminated to_int32 overhead for common loop indices
339339+340340+#### Sprint 1.4: Fast Path for Typed Array Access
341341+- Extended integer index fast path to typed array get/set
342342+- Typed array length already cached in Data_typed_array record
343343+- **Result**: Consistent optimization across all array types
