- Not exactly. Math.random () returns a pseudo-random number. This algorithm is called a pseudo-random number generator (or PRNG). This means its randomization can be reproduced under certain circumstances. The randomization is based on the algorithm xorshift128+, which is likely running on your browser. So, it’s random-ish.

Random Number Generation. Based on original algorithms developed at Wolfram Research, the Wolfram Language's core randomness generation is both highly efficient and of exceptional quality. The Wolfram Language can produce both discrete and continuous randomness, with a wide range of distributions conveniently specified in symbolic form.
