How to generate true randomness in JavaScript

How to generate true randomness in JavaScript

I’ve been wondering on this question for a little while now, and I don’t have like a reason to know this, I am just curious.

So we all know the Math.random() function in JavaScript. But this is not the answer, because I want to know how to generate a random number without this function, just pure randomness.

So, if you know an answer, please let me know.
