Javascript 如何将数据附加到JSON数组

我正在尝试为discord.js创建一个惩罚系统，当用户受到惩罚时，discord bot会将其记录在一个json文件中。惩罚是这样的：

{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}

{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}

{
  "punishments": [{
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }, {
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }]
}

{
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}

在我的populations.js文件中添加第二个惩罚后，它给了我如下内容：

{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}

{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}

{
  "punishments": [{
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }, {
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }]
}

{
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}{
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}

显然，这两种惩罚之间存在“预期文件结束”错误。 我曾尝试在网上浏览各种文档，但没有一个文档完全符合我的最终目标，即pumptions.json文件如下所示：

{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}

{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}{
  "username": "baduser#4567",
  "id": "baduser's id",
  "type": "Mute",
  "time": "<time>",
  "issued_by": "username: Admin#1234 id: admin id"
}

{
  "punishments": [{
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }, {
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }]
}

{
“惩罚”：[{
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}, {
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}]
}

TL；DR i需要一种在数组中附加这些惩罚的方法，最好的方法是什么？

var jsonObj={
var jsonObj = {
  "punishments": [
    {
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }
]
}

var newPunish = {
    "username": "baduser#4567",
    "id": "baduser's id",
    "type": "Mute",
    "time": "<time>",
    "issued_by": "username: Admin#1234 id: admin id"
  }

jsonObj['punishments'].push(newPunish)

“惩罚”：[
{
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}
]
}
var newpull={
“用户名”：“baduser#4567”，
“id”：“baduser的id”，
“类型”：“静音”，
“时间”：“，
“发布人”：“用户名：管理员#1234 id:管理员id”
}
jsonObj[“惩罚”].推（新惩罚）

谢谢，我正试图摆弄.push（），但没弄明白：v
