[tex4ht] why \newcommand has no effect when compiling to HTML using mathjax mode, why?

Because the \newcommand isn't included in HTML so MathJax cannot see
it. Moreover, it is quite possible that you will need different
command declarations for LaTeX and MathJax.

In the SVG mode, part of rendered DVI file is converted to image, the
DVI file contains result of full macro expansion, so it doesn't suffer
from such issues. MathML output also contains all commands expanded.

Best,
