what i'm trying to do: i'm trying to read a large csv, check for a true or false flag in each row if false i want to get that row do some operations and change the flag to true then move on to next row.
what i have been able to do:
i am able to read or write a file stream (using fs.createReadStream and fs.createWriteStream) from start to end (using json2csv and csvtojson in node.js). need to figure out a way to read to some operation if condition satisfy write/edit that row and move on
