DOMScope is a development software application that provides developers with a powerful way to quickly examine and debug the Document Object Model (DOM) of websites and web applications. It provides a visual representation of the DOM tree, including attributes, child elements, and other properties. It also provides an interactive console for running JavaScript commands, and an interface for inspecting the HTML and JavaScript code of the DOM nodes. DOMScope is a great tool for debugging and optimizing the structure of websites and web applications, as well as for troubleshooting complex JavaScript code.
