Hello Friends I hope you know about built in hooks in React
Custom Hook in React is basically a JavavScript function whose name starts with “use”
A custom Hook can also call other Hooks if required
Custom Hook Example
I have created custom hook to update title and this hook I can use in many other components anywhere
Use Custom Hook in Component
As you can see useDocumentTitle(countOne) is our custom hook we use with SetDocumentTitle() component
For any query you can ask in comment. Thanks for reading.
