Magicdom

Aug 8, 2017

Motivation DOM is the API that allows JavaScript to interact with HTML documents. The object that is a part of the DOM API is usually implemented as heap allocated C++/Rust object for most browsers. For JavaScript to interact with these objects, it needs to go through a wrapper called a reflector that gives JavaScript code access to the DOM object. For example, the DOM objects and reflectors on Servo is shown in Figure 1.
