* concatenation takes the contents of multiple assets and puts them in to a single file i.e. "output/main.js.
Given
the file "input/a.js" contains
var a = 1;
And
the file "input/b.js" contains
var b = 2;
#Concatenate!
the file "output/main.js" should contain
/* Made by Computer Corp. LLC */
var a = 1;var b = 2;

* bundle exec rake assets:precompile
This will create (by default) an assets directory in your public/ folder. It will then add all the compressed and compiled files into that directory, in the appropriate formats and with the new digested versions

*Minification refers to the process of removing unnecessary or redundant data without affecting how the resource is processed by the browser - e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on.

*The page rendered is a compiled version of all js in the application, whereas the file in our application is a placeholder for where these will be compiled

*A manifest uses directives to declare dependencies in asset source files. catch-em-all has application.js and application.css

*We use javascript_include_tag and stylesheet_link_tag and it gets used in layout/application

*Fingerprinting is a technique that makes the name of a file dependent on the contents of the file.
