在 NodeJS 中，“十进制”也可以用作“十进制”

Question

I am installing and using package decimal.js in NodeJS.

This package is described here .

All the examples state that I should be using Decimal . For some reason, it also works when using decimal .

What is the rationale behind this?

I've found a similar question on C# here , which states exactly what I sort of speculated:

The symbol decimal is declared as an alias for Decimal .

Is it the same in NodeJS, and how exactly do you go about aliasing something in JavaScript?

For the record, I am importing the package as follows:

import Decimal from 'decimal.js';

And as already implied, this seems to work just as well:

import decimal from 'decimal.js';

There are two different types of export. Named exports and Default exports.You can read more about it here .

From that Page: Named exports are useful to export several values. During the import, it is mandatory to use the same name of the corresponding object. But a default export can be imported with any name.
