While debugging this blog's theme files I encountered an mysterious "404 Not Found" HTTP error for file jquery.min.map when accessing the image file directly from the CDN. On further research it turned out this to be only specific when using "Chrome DevTools" which tries to load the file for debugging purposes, users won't be hitting this 404. It is also very easy to disable this JavaScript source maps completely from "Chrome DevTools" settings as shown below.

Disable JS Source Maps in Google Chrome Dev Tools :
Simply click the Gear configuration icon located in the bottom right corner of Chrome Dev tools and uncheck "Enable JS Source maps" option as shown below.
