OK, here is my function to turn CSV into JSON - what's yours?

CSVtoJSon.js

const csvToJSON = (csv) => {   
    const getcsvdata = (csv) => {
        const csvRegex = /,(?=(?:(?:[^"]*"){2})*[^"]*$)/;
        const trimQuotes = /^"|"$/g;
        csv = csv.split(csvRegex).map(
            h => h.trim().replace(trimQuotes, '')
        );
        return csv;
    }
    let lines = csv.split('\n');
    let headers = getcsvdata(lines.shift());
    let result = [];
    for (let line of lines) {
        let currentline = getcsvdata(line);
        result.push(headers.reduce((item, header, i) => {
            item[header] = currentline[i];
            return item;
        }, {}));
    }
    return result;
}

test.js

let csv = `Name, Age, City  
John, 21, New York
"Jane, Doe", 22, San Francisco
Jim, 23, Chicago
"Jill Chill", 24, "Tacoma, Seattle"`;

console.log(csvToJSON(csv));

Like the line shift. :)
