If you scratching your head and wondering what is Event Sourcing, this is a very good article to start. https://www.erikheemskerk.nl/event-sourcing-awesome-powerful-different/ I couldn't have explained it any better.

One of the common problems you common across while developing SPA or hybrid mobile apps locally is that when you make a cross domain API call, this is what you get in your console window XMLHttpRequest cannot load http://jsonplaceholder.typicode.com/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.  The reason for this is the browser security is preventing cross domain Ajax call. You can read more about CORS here . As a developer you don't want to worry about this and you just want to drink your coffee, write awesome code and test it your machine. Cool! I do the same! Here is a little secret. You can tell Chrome to ignore the security and allow cross domain request. To do this, create a new shortcut for Chrome and pass these parameters.   --disable-web-security --user-Agent="Android" --user-data-dir="c:/temp-chrome-eng" user-Agent is opt...

So there you go. Now you know what that little semicolon is doing there in your code.
