Multiply columns in CSV with jquery-csv

Question

I have some CSV that goes like UNIX timestamp, price (USD), amount traded (bitcoin). However, I also need the amount traded to be in USD, therefore I must multiply the 3rd column with the 2nd. Does anybody know how to do that?

Currently I'm using jquery-csv:

var originalCsv = `1366383202,748.680000000000,1.000000000000
1366471506,777.440000000000,2.700000000000
1368121200,685.740000000000,2.187400000000
1375783458,619.500000000000,1.000000000000`

// Parse multi-line CSV string into a 2D array
// https://github.com/evanplaice/jquery-csv

var newCsvTemp = $.csv.toArrays(originalCsv);

// jquery-csv's arrays are made up of strings, but we need them to be numbers

// Trim whitespace and then convert to Number

var newCsv = newCsvTemp.map(row => row.map(el => Number(el.trim())));

// Multiply amount traded with price

// var newCsvMultiplied = newCsv.map();

$(".new").text($.csv.fromObjects(newCsv));
$(".original").text(originalCsv);
