Decimal shouldn't be part of the interpreter. Even Python doesn't do that.

JS needs operator overloading so that it can have decimals, rationals, ndarrays, automatic differentiation, etc. Unfortunately operator overloading is a dirty word for most of the webblubs who use JS. I've given up hope of that ever changing.

Yeah, operator overloading would be a nice welcome change, and in the end the interpreter already does something similar because of all the coercion rules... Considering how JavaScript works behind the curtain, it seems to me that it wouldn't be such a huge change to just do something like Python's __add__ magic method

JavaScript inherited the abysmal standard library support of Lisp language families and poor support for domain specific use cases of Java. The situation has been improving, but with the ”never break the backwards compatibility” of the web browsers on the driver seat, JavaScript will never be like Python or Julia for the data science use cases.

Common Lisp supports actual fractions (integer ratios).

Floating point shouldn't be part of the interpreter. Integers are all you need.
