What are nuances and edge cases?

Nuances and edge cases are like little surprises that happen when things aren’t exactly what they seem.

Imagine you have a toy box full of blocks. Most of them fit together perfectly to build your favorite tower. But sometimes, there’s a block that’s just slightly bigger or smaller, not enough to stop you from building, but enough to make the tower wobbly if you don’t notice it. Those are nuances, tiny differences that matter in special situations.

Now imagine you're trying to stack all your blocks on top of each other, and one day you find a block that’s super big or super small. That block might not fit at all! That’s an edge case, something unusual that happens only sometimes but can change everything if it shows up.

When you're building towers, most of the time, you don’t need to worry about those tiny differences or that one weird block. But when things get tricky, like when you’re trying to build a really tall tower, those small differences and unusual blocks can become really important. That’s why it's good to know about them!
