const csv = data.map(item => `"${item.replace(/"/g, '""')}"`).join(',');
console.log(csv); // "He said ""Hello""","Example"

const data = ['First line\nSecond line', 'Example'];
const csv = data.map(item => `"${item}"`).join(',');
console.log(csv); // "First line\nSecond line","Example"

const data = ['Line1\fLine2', 'Example'];
const csv = data.map(item => `"${item}"`).join(',');

const data = ['你好', 'Example'];
const csv = data.map(item => `"${item}"`).join(',');
console.log(csv); // "你好","Example"

function escapeCsvField(field) {
    if (field.includes('"')) {
        field = field.replace(/"/g, '""');
    }
    if (field.includes(',') || field.includes('\n') || field.includes('\r')) {
        field = `"${field}"`;
    }
    return field;
}

const data = [
    ['Name', 'Message'],
    ['John Doe', 'Hello, "world"!'],
    ['Jane Doe', 'Line1\nLine2']
];

const csv = data.map(row => row.map(escapeCsvField).join(',')).join('\n');
console.log(csv);
// Name,Message
