使用ES6的传播将新的对象数组推入现有的对象数组

Question

Is this syntax even correct? results is my array of object, it's nested.

notifications: {
  ...state.notifications,
  results: [
    ...state.notifications.results,
    { ...state.notifications.results }
  ]
}

Answer 1

This should be work.

notifications: {
  ...state.notifications,
  results: [
    ...state.notifications.results
  ]
}

Answer 2

It seems to me that you're trying to run this.setState , and update your array whilst doing so.

The full command would be something like this:

this.setState({
  notifications: {
    ...this.state.notifications,
    results: [
      ...this.state.results,
      // whatever you're trying to add goes here
    ]
  }
});

I'm just guessing based upon the tags on your question. Feel free to comment and explain your situation further so I can tailor my answer to better suit your question.
