No but if you're using a lot of globals it tends to mean that you're not thinking in an optimal manner for JavaScript coding. Same when people rely on eval(). You need to think less about globals and more about objects, properties, and scopes. JavaScript is fundamentally object oriented, everything is an object... and most objects can contain every other kind of object... do instead of a global called myDataUrl, you could append a .data_url property to the object you created with that data. This way, each such object has that property, you don't have a tonne of globals to manage, and you can access the urls systematically. Generally speaking, a high number of globals signals that you don't understand JavaScript fundamentals and so you're likely doing things in a suboptimal way. THAT could result in slower code that's also hard to maintain code.
