Are there any equivalents of Sympy for JavaScript

Question

JavaScript

Good afternoon,
I wanted to know if there are analogues of Sympy ( www.sympygamma.com/ ) implemented in JavaScript.
I really need it on js, it will be fine if the library contains functionality only for integration.

Answer 1

and https://github.com/sympy/sympy-live did not please?

Answer 2

I am making an application on PhoneGap, i.e. dragging an interpreter for Python is expensive, it should work offline.
