REST API is quite simple and straightforward, used User ID to get user Title, Email for SharePoint 2013 and apps for SharePoint. use  /_api/web/getuserbyid(ID) to get the user field  in the response data, we have an “AuthorId” will get us the user Title, Email etc .

Step-1: Navigate to your SharePoint 2013 site and create a Wiki Page or a Web Parts page.

Step-2: The process to add your JavaScript code is quite straightforward:
Edit the page, go to the “Insert” tab in the Ribbon and click the “Web Part” option. In the “Web Parts” picker area, go to the “Media and Content” category, select the “Script Editor” Web Part and press the “Add button”.

Step-3: Once the Web Part is inserted into the page, you will see an “EDIT SNIPPET” link click. You can insert the HTML and/or JavaScript code into the dialog.

<script src="/Style Library/scripts/jquery-1.10.1.min.js"></script>

<script type="text/javascript">

  var userid= _spPageContextInfo.userId;

var requestUri = _spPageContextInfo.webAbsoluteUrl + "/_api/web/getuserbyid(" + userid + ")";

var requestHeaders = { "accept" : "application/json;odata=verbose" };

$.ajax({

    url : requestUri,

    contentType : "application/json;odata=verbose",

    headers : requestHeaders,

    success : onSuccess,

    error : onError

});

function onSuccess(data, request){

    var Logg = data.d;

    //get login name

    var loginName  = Logg.LoginName.split('|')[1];

    alert(loginName);   

    //get display name

    alert(Logg.Title);

}

function onError(error) {

    alert("error");

}

</script>

In the code above, we'll get the author id from the list. By passing the author id in to GetUserBuId() method, it will return the user in raw format like "I:O#.f|xxxx|xx@xxxx.com". We can get the login name by splitting the output.
