>+        This patch is changing the ``jsLess``` operation to follow the
>+        semantics of Abstract Relational Comparison[1] that supports BigInt.
>+        For that, we create 2 new helper functions ```bigIntCompareLess``` and
>+        ```toPrimitiveNumeric``` that considers BigInt as a valid type to be
>+        compared.
