声明一个无限对象的javascript数组

Question

如何声明一个可以包含无限量值的JavaScript对象，如下所示？我是Javascript的新手。

var activities = [
  {
    subject: "",
    genre :"",
    username: "",
    aboutuser: ""
  },
  {
    subject: "",
    genre :"",
    username: "",
    aboutuser: ""
  },
  {
    subject: "",
    genre :"",
    username: "",
    aboutuser: ""
  },
  ...
]

Answer 1

像这样：

  let myArray = []

  myArray.push({
    subject: "",
    genre :"",
    username: "",
    aboutuser: ""
  })

只需定义一个空数组，并将对象多次推入其中。
