   <dim:field mdschema="dc" element="description" qualifier="abstract" lang="en_US">JavaScript on the web is difficult to debug due to its asynchronous and dynamic nature. Traditional debuggers are often little help because the language's idioms rely heavily on non-linear control flow via function pointers. The aim of this work is to create a debugging interface that helps users understand complicated control flow in languages like JavaScript. This thesis presents a programming editor extension called Theseus that uses program tracing to provide real-time in-editor feedback so that programmers can answer questions quickly as they write new code and interact with their application. Theseus augments the call graph with semantic edges that allow users to make intuitive leaps through program traces, such as from the start of an asynchronous network request to its response. Participants in lab and classroom studies found Theseus to be a usable replacement for traditional breakpoint and logging tools, though no significant difference was found in their ability to complete programming tasks.</dim:field>
