Good q:

Why is OccourenceOrderPlugin a size optimization?😉 It has to do with module ids and topological sorting.

Great, thanks

What about more formal version?

q: Why the OccurenceOrderPlugin is the part of webpack optimisation. What it has to do with module ids and topological sorting?

a: OccurenceOrderPlugin order the modules and chunks by occurrence. More module occurs - smaller id it has, this technique helps to reduce bundle size.

I might elaborate and say because a module is used many times it will be referenced many times with webpack_require(moduleId)
