Like the process of inlining small CSS files, inlining small JavaScript files can provide similar benefits, like reducing the time it takes to fetch and download individual JavaScript files. It is important to note that this should be done in cases where it makes sense. One of the drawbacks of inlining CSS or JavaScript into HTML is that they are not typically cached, so the whole HTML document must be fetched every time. So, too much of a good thing is not always a good thing. Inline your JavaScript files where it makes sense and do not go overboard with it.
