Rearranging the slides

We can add the required methods for the SliderPuzzle.vue component by writing the following code:

<script>
...
export default {
  ...
  methods: {
    swap(index) {
      if (!this.timer) {
        return;
      }
      if (this.indexesToSwap.length < 2) {
        this.indexesToSwap.push(index);
      }
      if (this.indexesToSwap.length === 2) {
...
      this.resetTime();
      clearInterval(this.timer);
    },
    resetTime() {
      this.startDateTime = new Date();
      this.currentDateTime = new Date();
   ...
