Even if a binary DOM was the same size as HTML (it would actually be much smaller), eliminating the cost of parsing HTML (forgivingly) and serializing it into a DOM would be a significant improvement. Similarly, even if JS bytecode was the same size as the JS itself, eliminating the cost of parsing, constructing an AST, (possibly) transforming the AST, creating bytecode, and (possibly) doing an optimization pass on the bytecode would be significant.
