From what I’ve read, TC39 acknowledges that this is important and is working on fixing JavaScript’s deficiencies in this area:

– BigInts (arbitrary precision integers) were a recent addition: https://exploringjs.com/impatient-js/ch_bigints.html

– A proposal for `Decimal` (base 10 floating point numbers with arbitrary precision) is currently at stage 1: https://github.com/tc39/proposal-decimal
