If you're working with any jQuery-based plugins, then those scripts will certainly be dependent on jQuery and must be loaded after jQuery. It's rare that two different plugins will depend on each other unless specified. As for other site-specific scripts, it's always a good idea to include them last, so you can work with objects and variables defined in all libraries and plugins.
Ultimately, the best indicator for broken dependence is if you get "____ is undefined" errors in your browser console. That error is a good indication that the browser is missing required files or loading things out of order.

451 PointsAwesome, that is really helpful. Thank you.
Lets say I were to place this in the function.php folder: ''' wp_enqueue_script( 'main_js', get_template_directory_uri() . '/js/main.js', array('jquery'), '', true );
''' ...but it wasn't dependent on jquery, would that cause an error as well or cause other problems?

29,725 PointsNah, all you're really saying by declaring jQuery in the dependencies there is that you'd like WordPress to load main.js after jQuery. If main.js doesn't actually use anything from jQuery, it's no biggy. But you'll be set up to write your own jQuery-dependent code later on, which is good.
