That's not possible, no, at least not without a lot of complications that 
do not seem worth the price, compared to installing Node.js.  And note 
that even if that were feasible, it would only solve the first half of the 
problem: to transform a grammar.js file into its corresponding parser.c 
file, you also need the tree-sitter command line program.

Indeed, grammar authors are not limited to the standard Node.js API, they 
can import other libraries.  For example, tree-sitter-toml requires the 
regexp-util library.
