Generate random number between two numbers in JavaScript, Where is the pilot flying to? Use system random generator instead. This method is efficient, easy to implement and very convenient, Uniform distribution: the generated numbers should not repeat often, Hard to guess: generated numbers are not easy to predict, Efficient: does not take long time to generate, Deterministic: this is handy if we want to replay the generated numbers, Provides a step parameter to skip numbers, Computers are not random.

Why is "iron" pronounced "EYE-URN" but not "EYE-RUN"? What are the outcomes of this experiment? Have you ever thought about what random means or even if randomness makes any sense in the context of computing! For sequences, there is uniform selection of a random element, a function to generate a random permutation of a list in-place, and a function for random sampling without replacement. If you want to use a random number generator that is not reproducible, then you can use system random generator. Does Windows know physical size of external monitor?
