SOLID Principle:

Bundling and Minification

Bundling and minification techniques were introduced in MVC 4 to improve request load time

Bundling

Bundling allows us to load the bunch of static files from the server into one HTTP request

Minification

Minification technique optimizes script or CSS file size by removing unnecessary white space and comments and shortening variable names to one character.

What is Keep and Peek?

keep(): marks the specified key in the dictionary for retention.

peek(): returns an object that contains the element that is

associated with the specified key, without marking the key for

deletion.
