What are some common mistakes people make with destructuring in JavaScript?

Some common mistakes include not using the correct variable names, forgetting to use curly braces for objects, and trying to destructure undefined values.

Can you give me an example of incorrect destructuring?

Sure! If you try to destructure an object like this: const { a, b } = undefined;, it will throw an error because you can't destructure from undefined.

What about nested destructuring? Are there common mistakes there?

Yes, a common mistake is not matching the structure correctly. For example, if you have const obj = { x: { y: 1 } }; and you try to destructure it like this: const { x, y } = obj;, you'll get y as undefined because it should be const { x: { y } } = obj;.

How can I avoid these mistakes?

To avoid these mistakes, always ensure you're destructuring from defined values, use the correct syntax, and double-check the structure of the objects you're working with.
