Anatomy of a gulpfile
Before we can begin writing tasks, we should take a look at the anatomy and structure of a gulpfile. Examining the code of a gulpfile will allow us to better understand what is happening as we run our tasks.
Gulp started with four main methods: .task(), .src(), .watch(), and .dest(). The release of version 4.x introduced additional methods such as .series() and .parallel(). In addition to the gulp API methods, each task will also make use of the Node.js .pipe() method. This small list of methods is all that is needed to understand how to begin writing basic tasks. They each represent a specific purpose and will act as the building blocks of our gulpfile.
