You suggest to improve the overall TeX user experience, this is always a good idea, but here ,this is not stricto sensu a TeXworks issue.
IMO, it is not a good idea to control the user interface from the tex source.
In general this is considered good practice to clearly separate the tasks, and the tex source should never know anything about latexErrors.js.
Moreover, when sharing documents, using \typeout or \wlog for such a purpose would be considered as a pollution.
Finally, if you decide to change in latexErrors.js the way parameters are read, you will have to edit all the tex sources.

There must be another way to pass parameters from TeXworks to latexErrors.js.

BTW, if you think of a dedicated format of strings in the log file to be parsed by latexErrors.js (and possibly plain, context or so)
you might ask the TeXLive developers for a dedicated primitive in pdftex (and xetex, luatex)
It is something rather easy to implement, the benefits would be great IMO.
For example

would print to the log something like (to be improved)

end of TYPE
