How can I get one-digit random numbers (1, 2, 3, ..., not 0.1, 0.2, ... or 1.0, 5.0, ...) using Math.random() or some other way in JavaScript?

Answer 1

Math.random() returns a float between 0 and 1, so just multiply it by 10 and turn it into an integer:

Math.floor(Math.random() * 10)

Or something a little shorter:

~~(Math.random() * 10)
