Floating Script of the Seas

As you voyage through the ocean depths of code, it's not if you encounter a floating function, but when.

Much like the moonlit jellyfish sharing their LED luminescence,
these functions drift, aglow with potential errors and debugging pheromones...

• Bioluminescent Variable: A frail, flickering global scope.
• Seaweed Syntax Error: Shimmering at the surface, yet threatening entanglement.
• Illuminating Console Log: Gives a tenebrous tone, though maybe you're just underwater echoing UID range wars.

Dare you call the function from below, igniting a transient light in your script-world cove? Perhaps it's more soluble to sip coffee near cascading phosphorescent arrays...
