Pro Chunk optimization
If two chunks contain the same modules, they are merged into one. This can cause chunks to have multiple parents. If a module is available in all parents of a chunk, it’s removed from that chunk. If a chunk contains all modules of another chunk, this is stored. It fulfills multiple chunks.
Con Dynamic loading
The module syntax addition (import x from 'xyz') is intentionally designed to be statically analyzable, which means that you cannot do dynamic imports.
