如何在 node.js 中为对象动态添加属性？

Question

我有一个对象，我希望能够在其中动态添加至少一个属性。 属性的数量取决于我拥有的数组中的项目。 这是我引用的对象：

const helpEmbedMsg = new global.Discord.MessageEmbed()
                // Display a different (random) color every time the command is used.
                .setColor("RANDOM")
                .setTitle("Help")
                .setAuthor("Beatrice~")
                .setDescription("A full list of the commands available to you..")
                .addFields(
                    { name: `The current __prefix__ for this server is:   \`${prefix}\``, value: "\u200B" },
                )
                .addField("📋 Here's a list of all my commands:", "\u200B", false)

                .addField("\u200B", "\u200B", false)
                .addField(`Type \`${prefix}help <command>\` to learn more about a command and it's usage!   `, `Example: \`${prefix}help ping\``, false)
                .setTimestamp()
                .setFooter(`Command triggered in ${message.channel.guild}`);

所以，基本上，如果数组的长度是 4，我想添加以下内容：

.addField(array[i], "text here", true)

四次，但在对象中的特定位置（顺序计数），就在此行下方：

.addField("📋 Here's a list of all my commands:", "\u200B", false)

因此，只需将代码分成两个链，并在它们之间使用for循环：

const helpEmbedMsg = new global.Discord.MessageEmbed();

helpEmbedMsg.setColor("RANDOM")
    .setTitle("Help")
    .setAuthor("Beatrice~")
    .setDescription("A full list of the commands available to you..")
    .addFields(
        { name: `The current __prefix__ for this server is:   \`${prefix}\``, value: "\u200B" },
    )
    .addField("📋 Here's a list of all my commands:", "\u200B", false);

// add an array of properties in this specific order
for (let item of array) {
    helpEmbedMsg.addField(item, "text here", true);
}

// add the rest    
helpEmbedMsg.addField("\u200B", "\u200B", false)
    .addField(`Type \`${prefix}help <command>\` to learn more about a command and it's usage!   `, `Example: \`${prefix}help ping\``, false)
    .setTimestamp()
    .setFooter(`Command triggered in ${message.channel.guild}`);
