Analyze the impact of loading external JavaScript resources. The tool compares the global object before and after script execution to identify newly added globals to help developers understand what a script exposes to the global scope.

Import Inspector complements global state diff by allowing users to specify a module URL and inspecting its exported bindings. It dynamically imports the module and lists all named and default exports, giving a clear view of what’s available for consumption.
