Transform string into operation

Question

I need to transform a string like "5+4+8*6(4)" as an operation, after it, I will be able to calculate it (here 5+4+8*6(4) = 201)

Answer 1

I advise you to use the mathjs library http://mathjs.org/docs/expressions/parsing.html

var result = math.eval('5+4+8*6(4)');
