Solve an arithmetic string in javascript?

Question

suppose I have the following code:

    var str = "4*(3)^2/1"

Is the simplest solution just to make a stack of the operators and solve with postfix notation? Or is there a really basic solution I'm missing.

Additionally how can I adapt if I'm using log, ln, sin, cos, and tan?

Answer 1

Sorry to respond to my own question, but the easiest solution is using math.js

    var ans = math.eval(str);
