Every beginner game dev's first encounter with deltaTime is just blindly sprinkling it everywhere like seasoning on soup. The tutorial says "multiply by deltaTime for frame-independent movement" and you're just nodding along pretending you understand why your character moves at warp speed without it. You don't know why it works, you don't know how it works, you just know the angry red cube stops teleporting across the screen when you add it. It's basically the "turn it off and on again" of game loops – works every time, questions never. Fun fact: deltaTime represents the time elapsed between frames (usually in seconds), which ensures your game runs at the same speed whether someone has a potato PC running at 30 FPS or a beast rig pushing 240 FPS. Without it, your game speed would be tied to framerate, making it unplayable on different hardware. But yeah, as a kid you just threw it in there like magic fairy dust.
