What is the difference between iterable and iterator in JavaScript?
An example of an AI chatbot conversation about the difference between iterable and iterator in JavaScript.
Can you explain the difference between iterable and iterator in JavaScript?
Sure! An iterable is an object that can be iterated over, like arrays or strings. An iterator, on the other hand, is an object that provides a way to access the elements of an iterable one at a time.
Can you give me an example of an iterable and an iterator?
Absolutely! An array is an iterable. You can use the Symbol.iterator method to get its iterator, which allows you to traverse the array elements using the next() method.
How do I create my own iterable in JavaScript?
You can create your own iterable by defining a Symbol.iterator method in your object. This method should return an iterator object with a next() method.
What happens if I try to use an iterator on a non-iterable object?
If you try to use an iterator on a non-iterable object, you'll get a TypeError because the object does not have a Symbol.iterator method.
