I'm not so sure that the Javascript (well, EMCA Script) LANGUAGE is the problem. The challenges with respect to rendering speed have more to do with the DOM and the interaction with the browser itself. The DOM is a bulky beast. When javascript listeners are assigned to page elements the code can in turn alter the DOM creating or destroying elements, all of which can trigger javascript functions, any of which can create or destroy more DOM elements. It's a properly tangled mess. Memory management in this environment is no small task.
