I have some experience using both of these libraries, so I will do my best to explain each of them:
Intl.NumberFormat and decimal.js are both libraries in JavaScript that can be used to format and manipulate numbers. However, while they are similar in some ways, they are very different in others.
Intl.NumberFormat is a built-in JavaScript library that provides localization support for number formatting, including decimal and grouping separators, decimal precision, and currency formatting. It is widely used to format numbers based on a user's language and region.
Decimal.js is a third-party library that provides arbitrary-precision decimal arithmetic for JavaScript. It allows for precise calculations with decimal numbers, which are often required in financial and scientific applications where rounding errors can have significant consequences.
Although Intl.NumberFormat can handle basic currency formatting, it may not be suitable for all use cases. For example, it may not handle more complex currency formatting requirements, such as rounding rules or multiple currencies in the same document. In such cases, decimal.js can provide more precise and flexible currency handling capabilities.
I hope this answered your question!

I agree to Promaster's answer, it's also worth noting that using the decimal.js library may have performance implications, as it is a third-party library that requires additional processing overhead compared to the built-in Intl.NumberFormat library. Therefore, you should consider the specific requirements of your application when deciding whether to use decimal.js or Intl.NumberFormat.
The main benefit of using the decimal.js library over Intl.NumberFormat is the ability to perform precise mathematical operations on decimal numbers. If your application requires this level of precision, then decimal.js may be a better choice. However, if your application only requires formatting numbers for display, then Intl.NumberFormat may be sufficient.
Hey Node Friends. I'm going to have to build a system that deals with currency and money arithmetic for the first time. We are all aware that using floating points is problematic for these sort of calculations.
Is there a preferred library by the community that deals with this stuff?
The best I've found on my own is big.js
Update: Unlike the comments below, I didn't use float or integers as that is what I was trying not to use in the first place.
mathjs was a suggestion, but that depends on decimal.js anyway so you could just use decimal.js directly.
I read over this comparison between decimal.js, big.js and bignumber.js. I went with big.js in the end, just because it's the more minimal version of the 3 that does everything I need (ex. I only need to use base 10)
Thanks for the help!
