With Site24x7 RUM, you can contextually debug JS errors by analyzing their frequency over time. This helps you to correlate and narrow down to the root cause of specific issues. 

Let's look at the example below.

From the image above, you can see that the number of Type Errors was initially low. After that, there was a gradual increase and a sudden peak which was subsequently contained. This variation may have been caused by product enhancements, new build updates, or some other change. By viewing the error trends over a period of time, you can easily narrow down the root cause of issues. 

You can also debug browser-specific JS errors with Site24x7 RUM. Learn more.
