How do i extrapolate function name in javascript?

Question

I have this

Subject.books()

that works great, but now at one place in code i just have the string 'books()', this string could basically be anything you want, i just want it to eval and evaluate the function and give me the same result as above. How do i do it?

Do you have string 'books()' i.e. with brackets or just 'books'? — ihor marusyk, Jul 11 '13 at 12:10

Square bracket notation:

Subject['someString']();
