Answer 1

You can delete them, read the following lines:

CSS

Laravel Elixir provides a clean, expressive API over compiling SASS or Less, which are extensions of plain CSS that add variables, mixins, and other powerful features that make working with CSS much more enjoyable.

In this document, we will briefly discuss CSS compilation in general; however, you should consult the full Laravel Elixir documentation for more information on compiling SASS or Less.

JavaScript

Laravel does not require you to use a specific JavaScript framework or library to build your applications. In fact, you don't have to use JavaScript at all. However, Laravel does include some basic scaffolding to make it easier to get started writing modern JavaScript using the Vue library. Vue provides an expressive API for building robust JavaScript applications using components.
