title: Append array of values to the current array in a state in React JS
body: <p>I have the state values as </p>
  
  <pre><code>this.state = {
      emp: [
          {id: "1", name: "A"}
          {id: "2", name: "B"}
          {id: "3", name: "B"}
      ]
  }
  </code></pre>
  
  <p>How can I add an array like <code>var arr = {id:"4", name:"D"}</code> to the state <code>emp</code> without removing the current values of array. I just want to append the new array of values to the current state array. Can anyone help?</p>
