How does mathjs.create work?

mathjs.create() is a function provided by the Math.js library that creates a new Math.js instance with its own configuration and namespace, which can be used independently of other instances or the default Math.js instance. When called, it returns a new instance of the Math.js library with the provided configuration and namespace. The new instance can then be used to perform mathematical operations using the provided namespace.

const math = require("mathjs");

// create a new instance of MathJS
const newMath = math.create();

// define a new constant in the new instance
newMath.import({
  myConstant: 42,
});

// use the new constant
const result = newMath.evaluate("myConstant + 1"); // 43

In this example, mathjs.create() is used to create a new instance of the mathjs library, which can be customized with additional functions and constants. In this case, a new constant myConstant is defined in the new instance and used in an expression.
