(b) Sends the source to the Math Library

(c) Returns the value of the object

(d) Returns an integer value

I have been asked this question in unit test.

The origin of the question is Comparison of Core JavaScript versus Frameworks in portion Caching, Debugging and Animation of JavaScript

Answer 1

Right option is (a) Returns the string “Math”

Best explanation: The method Math.toSource() returns the string “Math”. But this method does not work with many browsers like IE. The toSource() method returns a string representing the source code of the object.
