optimize numeric operators in JS
See original GitHub issueA part of #5812 that wasn’t explicitly stated in the issue description, but that @chochos and I had talked about, was optimization of the numeric operators +
, -
, *
, /
. Currently they still compile down to the relatively expensive method calls plus()
, times()
, etc.
Note that we can probably only do this when the static type of both operands is exactly Integer
or Float
. (Not sure about Byte
.)

This is now done, native operators are used wherever reasonable, and there is no boxing of
Float
