Which version of Webpack should I start learning?

Question

webpack

I want to learn how to work with Webpack, and the 4th version was recently released. Start learning the third or fourth version?

Answer 1

Write your projects on the 4th, if there are problems, put the older version.
For a stable project, if the deadlines are burning, I would take the 3rd.
On support, both 1st and 2nd are still found (well, this is a "cap")
