如何使数组值以逗号分隔

let array = ['apple', 'banana', 'cherry'];
let string = array.join(', ');
console.log(string); // 输出: apple, banana, cherry

array = ['apple', 'banana', 'cherry']
string = ', '.join(array)
print(string)  # 输出: apple, banana, cherry

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        String[] array = {"apple", "banana", "cherry"};
        String string = String.join(", ", array);
        System.out.println(string); // 输出: apple, banana, cherry
    }
}

using System;

class Program {
    static void Main() {
        string[] array = { "apple", "banana", "cherry" };
        string stringArray = string.Join(", ", array);
        Console.WriteLine(stringArray); // 输出: apple, banana, cherry
    }
}

let array = ['apple', null, 'cherry'];
let string = array.map(item => item || '').join(', ');
console.log(string); // 输出: apple, , cherry
