Do you mean a lot of objects?  Or do you mean calls to getProperty and 
setProperty (the JSClass hooks)?  I don't see how JS_GetProperty and 
JS_SetProperty enter into it.

An object per row is necessary.  Alternatively, if you could rewrite the 
script, or have authors write it this way themselves, you could identify 
elements in the 2d array using identifiers such as '0,1' and '1,1' -- in 
other words, use string identifiers that concatenate the row and column 
indexes with a ',' in between.
