It's not just JavaScript with that issue... https://0.30000000000000004.com/

Not if you use decimal type that is not available in JavaScript.

I'm curious what you're comparing JavaScript to. Decimal is the native numeric datatype for the stored procedure language of the database I use. Otherwise, even in languages that have a decimal class in their standard library, it's usually pretty clunky to use; no better than, say, https://github.com/MikeMcl/decimal.js/ C# is perhaps the best among mainstream languages, although its implementation is a bit weird.
