In this chapter, we learned how to create a simple JavaScript build system using Node.js with Gulp. We also explored other plugins and checked out Grunt Task Runner, which works similar to Gulp but contains many more plugins for your work.
Build systems help your performance greatly without much effort; keep in mind that gulp files can be reused for other projects, and so experiment and find out what works best for your projects.
In the next chapter, we will learn tips and tricks on how to use Chrome's Developer tools option to better optimize our web application code.
