How code splitting works in webpack?

1. get the chunkIds and moreModules
2. for each chunkId, if the chunk is previously cached, use that cached version
3. load all the modules in moreModules
4. run __webpack_require__.e when needed
   1. find the head, create the script tag
   2. send a JSONP request, get the code
   3. append the script to the head
