How to make background from dots on canvas?

Question

JavaScript

It is necessary to implement an animated background of dots, as on https://hdactech.com on the first screen on a blue background.
On the canvas, as far as I understand, this is the easiest to do.

Interested in any options - ready-made solutions, examples, libraries, generators, articles, etc.

What's the problem with opening the console and seeing how it's done? You can even drag it to you .
