An example of an AI chatbot conversation about common promise errors in JavaScript.
What are some common errors when using promises in JavaScript?
Some common errors include forgetting to return a promise, not handling rejections, and chaining promises incorrectly.
Can you explain what happens if I forget to return a promise?
If you forget to return a promise, the calling function won't wait for the promise to resolve, leading to unexpected behavior.
What about handling rejections? Why is it important?
Handling rejections is crucial because unhandled promise rejections can crash your application or lead to silent failures.
How can I properly chain promises?
To chain promises, ensure each .then() returns a promise, allowing the next .then() to wait for its resolution.
Are there any tools to help debug promise issues?
Yes, tools like Chrome DevTools and libraries like Bluebird provide helpful debugging features for promises.
