Overscripted! Digging into JavaScript execution at scale

We set out to explore the unseen or non-obvious JavaScript execution events that are triggered when a user visits a webpage, and all the first- and third-party events that are set in motion when people retrieve content. To help enable more exploration and analysis, we are releasing our full set of data about JavaScript executions. This post introduces the dataset, how it was collected, and the decisions made along the way. We’ll share examples of insights discovered and provide information for participating in the associated Overscripted Web: A Mozilla Data Analysis Challenge, which we’ve launched today with Mozilla’s Open Innovation Team.
