Converting moment.js to vanilla JavaScript with `.toLocaleDateString()`

component-sans-moment.js

// This is meant to be a Vue component, cause my site https://henry.codes is built with Nuxt.js. I put the .js extension on there for that fresh Gist syntax highlighting.
export default {
  computed: {
    postDate() {
      return new Date(this.post.fields.publishDate).toLocaleDateString("en-US", { month: "short", year: "2-digit" });
    }
  }
};

component-with-moment.js

import moment from 'moment';
export default {
  computed: {
    postDate() {
      return moment(this.post.fields.publishDate).format("MMM YY");
    }
  }
};
