<script type="text/javascript">  
//The below example gets the root folder of the Documents library and create a subfolder name as "NewFolderName" under it.
$pnp.sp.web.lists.getByTitle("Documents")
    .rootFolder
    .folders
    .add("NewFolderName").then(function(data) {
        console.log(data);
        document.getElementById("folderInfo").innerHTML = "Folder created successfully.";
    }).catch(function(err) {
        console.log(err);
        document.getElementById("folderInfo").innerHTML = "Unable to create Folder.";
    });
</script>

Typescript Example:

Typescript is the superset of JavaScript and this PnP JS library is developed using the typescript specification. For developing the SharePoint Framework web parts and make the client side development easier, we can vote for typescript. The below is the typescript example for creating a new folder under root folder of the SharePoint List / Library.

import pnp from "sp-pnp-js";

pnp.sp.web.lists.getByTitle("Documents").rootFolder.folders.add("NewFolderName").then(data => {
    this.domElement.querySelector("#folderInfo").innerHTML = "Folder created successfully."
}).catch(err => {
    this.domElement.querySelector("#folderInfo").innerHTML = "Unable to create Folder."
});
