How to constantly generate an array with random but close numbers in Javascript?

Task:
I have an interval function that generates a new array every second with random numbers.
I need random numbers, but so that they are close in value. Something similar to a processor performance meter. That is, the numbers are constantly jumping, but they do not go far from each other.
Current result: the numbers are generated quite randomly.
Desired result: the numbers are generated within a close value
Something like this:
What is at the moment:
function generateNumberArray(min, max, arrayLength) { let randoms = Array.from({ length: arrayLength }, () => Math.floor(Math.random() * (max  min + 1) + min) ); return randoms; } const usersChoiceTanks = setInterval(() => { socket.emit("usersChoiceTanks", generateNumberArray(10, 80, 8)); }, 1000);

There is Perlin Noise (Simplex Noise 2D) returning numbers in the interval
[0; 1]
, or in the range[1; 1]
, depending on the implementation. If you find one that returns numbers in the[1; 1]
, then turn it into an interval[0; 1]
(divide the resulting number by 2 and add 0.5) and multiply by a certain coefficient.Anonymous
