Exception and debugging behaviors for JavaScript debugging using just my code

摘要

Just My Code debugging allows developers to work on problems within their own code without noise from libraries, plugins and other unrelated code. Typical debugger behaviors may be modified based upon the identification or characterization of JavaScript code as “My Code,” “Library Code,” or “Unrelated Code.” The debugger behaviors that may be modified depending upon the code's characterization include, for example, first-chance exception handling, unhandled exception handling, the behavior of the debugger at explicit user breakpoints, the behavior when a user directs the debugger to break upon the next statement, and the behavior of the debugger when the user executes a stepping gesture. The debugger's visualizes core elements of the program state, such as the call stack, depending upon the identification or characterization of the code.
