Question 1

How to evaluate user input expressions safely with Math.js?

Accepted Answer

Use the evaluate function with sanitized input to prevent injection attacks; Math.js provides expression parsing but doesn't include built-in security features, so validate inputs externally. Refer to the documentation for best practices on handling dynamic expressions.

Question 2

Math.js vs numeric.js for numerical computing in JavaScript?

Accepted Answer

Math.js is more comprehensive with symbolic computation and diverse data types, while numeric.js focuses on fast numerical algorithms for linear algebra. Choose Math.js for flexibility and expression parsing, but numeric.js for performance-critical numeric operations.

Question 3

Can Math.js handle symbolic integration?

Accepted Answer

No, Math.js supports symbolic differentiation and algebraic manipulation, but not symbolic integration out of the box. For integration, you might need to combine it with custom logic or look at other libraries like algebra.js for limited cases.

Question 4

How to reduce bundle size when using Math.js in a web app?

Accepted Answer

Use tree-shaking with ES modules or load only specific functions via math.create, as mentioned in the Build scripts section. This allows importing only necessary dependencies to minimize footprint.

Question 5

Is Math.js suitable for real-time calculations in games?

Accepted Answer

It can be used, but the overhead from expression parsing and mixed data types might slow down performance. For game physics or animations, consider lightweight alternatives or pre-compile expressions for better speed.

Question 6

How to extend Math.js with custom data types?

Accepted Answer

Follow the steps in the 'Implementing a new function' section: create typed functions, use dependency injection, and update TypeScript definitions. This requires understanding the architecture but enables seamless integration.
