Experimental features in web browsers refer to functionalities currently in the testing phase and are not yet fully stable or standardized.

This helps them refine the features before officially releasing them, leading to a better user experience for everyone.
• Identify potential issues: Experimental features act as a testing ground to uncover bugs and performance issues before they impact a wider user base. Developers can monitor how users interact with the features and address any problems that arise before the official release.
