What are the differences between async validators in JavaScript frameworks?
Async validators are used to validate data asynchronously, often in forms. Different frameworks implement them in unique ways.
Can you give examples of frameworks that use async validators?
Sure! Popular frameworks like Angular, React, and Vue.js all have their own implementations of async validators.
How does Angular handle async validation?
In Angular, async validators return an observable or a promise that resolves to either null (valid) or an error object (invalid).
What about React? Is it different?
Yes, in React, async validation is often handled using hooks like useEffect, where you can manage state and side effects.
Which framework do you think has the best async validation approach?
It depends on your needs! Angular's built-in support is robust, while React offers more flexibility with custom hooks.
