Which of the following are considered top errors in an application?

The identification of top errors in an application is critical for maintaining performance and user experience. In the context of the provided choices, focusing on requests and JavaScript errors captures two prominent aspects of web application functionality.

Requests are fundamental to the operation of web applications, as they encompass all interactions between the client and the server. Failure in requests can lead to significant disruptions in user experience, including error messages, failed page loads, and incomplete data retrieval. Identifying and addressing issues with requests typically involves examining response codes, connection timeouts, and server errors, all of which are crucial for application health.

JavaScript errors, on the other hand, occur in the client-side code and can prevent scripts from executing correctly, potentially leading to a broken UI or non-responsive features. These errors can result from syntax mistakes, referencing unavailable objects, or issues with asynchronous calls. Since JavaScript is fundamental to adding interactivity and functionality to web applications, resolving these errors is key for ensuring that users can effectively engage with the application.

Focusing on both requests and JavaScript errors allows for a comprehensive understanding and monitoring of application health, making it essential for troubleshooting and optimizing performance.
