How do I sort this array by date?

I'm trying to sort the dates from this external API in my latestResults array by latest on top to oldest on bottom but can't seem to figure out how.
Right now they're displayed with the oldest date first and it's working fine, but it's in the wrong order for me.
I tried using result in latestResults.reverse() but that just reverses the 7 items currently in the array.

HTML:

<div v-for="result in latestResults" v-bind:key="result.latestResults">
      <small">{{ result.utcDate }}</small>
</div>

Script:

     <script>
    
    import api from '../api'
    
    export default {
    
        data () {
        return {
          latestResults: [],
          limit: 7,
          busy: false,
          loader: false,
        }
      },
    
        methods: {
    
            loadMore() {
                this.loader = true;
                this.busy = true;
            api.get('competitions/PL/matches?status=FINISHED')
            .then(response => { const append = response.data.matches.slice(
                this.latestResults.length,
                this.latestResults.length + this.limit,
                this.latestResults.sort((b, a) => {
                    return new Date(b.utcDate) - new Date(a.utcDate);
                })
            );
            setTimeout(() => {
            this.latestResults = this.latestResults.concat(append);
            this.busy = false;
            this.loader = false;
        }, 500);
        });
      }
    },
    
    created() {
        this.loadMore();
      }
    }
    
    </script>

The JSON where I'm getting matches like this that has utcDate:

    {
    "count": 205,
    "filters": {
        "status": [
            "FINISHED"
