1. Cross Origin means different origins (github.com or javascript.info) You are not allowed to share data from one origin to another origin.

2. When you want to share the data form one origin to another you will have to implement something called CORS - policy on the server. Something like (github is allowed to use data from javascript.info)

3. When you have CORS issue from origin null you have to use live(parcel, webpack etc) server to build the website.

4. You can also use CORS proxy something like https://cors-anywhere.herokuapp.com/. Proxy is something that acts like a middleware where you send request to the proxy url and that url send request to the server you are trying to access. Don't use it on production
