Does that mean that if the js file is on the bottom it will load for the user what is necessary to see, but in the meantime, it will still be loading before the user ever clicks on something javascript will be fully loaded that it will work?

230,688 PointsIn modern browsers, JavaScript loaded at the bottom of the page code will be loaded after the DOM is constructed in memory, but it will be run to completion before the page is rendered on the user's screen.
So when you see any buttons, all the JavaScript code (except anything asynchronous or event-driven) has already been done.
