Getting column names with d3.csv

d3.csv.js

<script type="text/javascript">
        
        /*
            Example cars.csv:
            
            Year,Make,Model,Length
            1997,Ford,E350,2.34
            2000,Mercury,Cougar,2.38

         */
        
        d3.csv('cars.csv', function(csv) {
            csv.forEach(function(row) {
                console.log(Object.keys(row));
            });
        });

        /*
        
        For each row outputs: ["Year", "Make", "Model", "Length"] 

         */
    </script>

d3.csv('cars.csv', function(csv) {
    console.log(csv.columns);  // ["Year", "Make", "Model", "Length"]
});

@hatemhosny your method wasn't working. Here is the correct way to read in a csv file and get the column names:

d3.csv('csv/analytic_data2010.csv').then(function (data) { console.log(data.columns); });

Here is the link to the source: https://github.com/d3/d3-fetch/blob/master/README.md#installing. The only thing I added is the .columns.
