Mar 12, 2018 · Surprise surprise, the answer is that Math.random() doesn’t really generate a random number. Not exactly. It just does a really good job of simulating randomness. Algorithmic random number generation can’t exactly be random, per se; which is why they’re more aptly called pseudo-random number generators (PRNGs).
Dec 2, 2021 · 2. You can use getTime() for that like that, if length doesn't matter for your, if it does, use .slice() method but before using it convert it in string using .toString() const randomNumber = parseInt(new Date().getTime()) console.log(randomNumber) answered Dec 2, 2021 at 7:35. xhxe.

The Math.random() static method returns a floating-point, pseudo-random number that's greater than or equal to 0 and less than 1, with approximately uniform distribution over that range — which you can then scale to your desired range. The implementation selects the initial seed to the random number generation algorithm; it cannot be chosen or rese...
Parameters Return value
A floating-point, pseudo-random number between 0 (inclusive) and 1 (exclusive).
Note that as numbers in JavaScript are IEEE 754 floating point numbers with round-to-nearest-even behavior, the ranges claimed for the functions below (excluding the one for Math.random() itself) aren't exact. If extremely large bounds are chosen (253 or higher), it's possible in extremely rare cases to reach the usually-excluded upper bound.

Mar 15, 2018 · So a random number generator is often a cipher that keeps getting re-seeded with more randomness, as it can be attained. By comparison, a simple [0,1] random number generator can't have more entropy than the number of bits in the number; and will typically have an odd distribution that isn't exactly what you want as well.
Mar 17, 2022 · In most browsers, Math.random () is implemented using a pseudo-random number generator (PRNG). This means that the random number is derived from an internal state, mangled by a deterministic algorithm for every new random number. It seems random to the user because the algorithm is tuned in such a way that it appears so.

Description. The Math.random() method returns a random floating point number between 0 (inclusive) and 1 (exclusive). Math.random () does not return a cryptographically secure number. If you need a cryptographically secure number, use this Crypto API method:
