What can Gulp do without plugins?

Question

gulp.js

Hey!
what can be done with a freshly installed Gulp without additional plugins?
for a site on html + css
Is it possible to do something with preprocessors, for example, use SASS and get CSS from it. Or something else...

Answer 1

Gulp is basically a task runner. He does not know how to do anything except how to run tasks. It can run them sequentially or in parallel, it can transfer the data stream from one task to another, it can write this data to a file. This is where his possibilities end. He can't do anything else. The functionality that it provides allows you to conveniently organize a large number of small programs that may be needed when building or deploying a project, but the programs themselves do not concern it. He was told to launch - he launches, nothing more.
Further, we can already make programs, tasks, for our tasks, including supplementing them with plugins for Gulp, which, in essence, are the same independent programs that simply comply with certain agreements on how to work with data input and output.
