Random text generator

Question

What is the best way to generate a random string consisting of alphabets and its maximum of 8 million characters to be tested using string search algorithms? Is Math.random still ok for randomness or robustness based on statistics? any comment is appreciated, correctly, if I am mistaken in my ideas.

Answer 4
