In that case, you probably don’t notice much difference. But the SVG spec creates objects just like HTML does, and just like HTML, you can bind events and attributes to those objects, and can do some very useful interactive stuff The 4D SVG component and the 4D language don’t have any direct way to apply events to individual objects in an SVG area. With Javascript, this is easy. It is object oriented. Each SVG object can contain its own event handlers and attribute data. Objects can inherit prototype traits. Objects can nest inside each other. The language is built for this stuff. An example of the difference would be in an implementation of drag and drop in SVG. You can do it with 4D, but it takes quite a few lines of code. Its pretty awkward, especially if there are a lot of objects. The same problem in javascript is simple and elegant and fast.
