The below example creates a new index for the field in a SharePoint List. We can also achieve it for SharePoint Library.


<script type="text/javascript" src="/siteassets/scripts/fetch.js"></script>
<script type="text/javascript" src="/siteassets/scripts/promise.min.js"></script> 
<script type="text/javascript" src="/siteassets/scripts/pnp.min.js"></script>
  
<span id="outputInfo"></span>

<script type="text/javascript">  
//The below example updates the Title field as Index in SharePoint List.
$pnp.sp.web.lists.getByTitle("TestList").fields.getByTitle("Title").update({
    Indexed: true
}).then(function(resp) {
    document.getElementById("outputInfo").innerHTML = "Index created for the Title field";
}).catch(function(err) {
    document.getElementById("outputInfo").innerHTML = "Unable to create Index.";
});
</script>

Typescript Example:

Typescript is the super set 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 index for the Title field from the SharePoint List.

import pnp from "sp-pnp-js";

pnp.sp.web.lists.getByTitle("TestList").fields.getByTitle("Title").update({
    Indexed: true
}).then(data => {
    this.domElement.querySelector("#outputInfo").innerHTML = "Index created for the Title field."
}).catch(err => {
    this.domElement.querySelector("#outputInfo").innerHTML = "Unable to create Index."
});
