Creating Pages From Markdown Files

@Jack I would recommend you read this very interesting article about what's best for each case: https://medium.com/better-programming/should-i-use-promises-or-async-await-126ab5c98789

Is there any disadvantage to using async await syntax rather than the Promise one used in the video? The following code seems to work identically:

const path = require("path");

exports.createPages = ({ graphql, actions }) => {
  const { createPage } = actions;

  const createPagesFromMarkdown = async () => {
    const { data } = await graphql(`
      {
        allMarkdownRemark {
          edges {
            node {
              frontmatter {
                slug
              }
            }
          }
        }
      }
    `);

    const markdownPages = data.allMarkdownRemark.edges;

    markdownPages.forEach(({ node }) => {
      createPage({
        path: node.frontmatter.slug,
        component: path.resolve("./src/components/postLayout.js"),
      });
    });
  };

  return createPagesFromMarkdown();
};

Hi, Why exactly do we want it to be async?
