Question

If you import a javascript file that calls jQuery.noConflict(), will that cause errors with scripts you made that depend on jQuery’s $ shortcut?

Answer 1

Yes, it will, as it will return $ to whatever it pointed to previously (possibly undefined).

You could always encapsulate your code with…

(function($) {
    // `$` in here points to `jQuery` and `$.noConflict()` won't affect it.
}(jQuery);
