To build a fast and responsive web application we minified the  JavaScript files.  In other cases, such as JavaScript plugins, jQuery framework or even on demand code library are minified to be used directly. While this is good for performance,  one of the challenges of working with the minified version of file is,  it becomes really hard to read and debug. Because they are not properly  formatted and aligned.
