An example of an AI chatbot conversation about common mistakes with the spread operator in JavaScript.
What are some common mistakes when using the spread operator in JavaScript?
One common mistake is using the spread operator on non-iterable objects, which will throw an error.
Can you give me an example of that?
Sure! If you try to spread an object like this: const obj = {a: 1}; [...obj], it will result in an error because objects are not iterable.
What about using it with arrays?
When using it with arrays, a mistake is not realizing that it creates a shallow copy. Nested objects will still reference the original.
How can I avoid these mistakes?
To avoid these mistakes, always check if the object is iterable and be mindful of shallow copies when dealing with nested structures.
