Bundling and minification are two new techniques introduced to improve request load time. It improves load time by reducing the number of requests to the server and reducing the size of requested assets (such as CSS and JavaScript).
Bundling: It lets us combine multiple JavaScript (.js) files or multiple cascading style sheet (.css) files so that they can be downloaded as a unit, rather than making individual HTTP requests.
Minification: It extracts the whitespace and performs other types of compression to make the downloaded files as small as possible. At runtime, the process recognizes the agent of the user, for example, IE, Mozilla, etc. and then removes whatever is specific to Mozilla when the request comes from IE.
