Hi,

To get version of the SharePoint list items; there are two option in JavaScript

1. SPServices

$().SPServices({
            operation: "GetVersionCollection",
            async: false,
            strlistID: "Deviations",
            strlistItemID: DID,
            strFieldName: "PreventionDescription",
            completefunc: function (xData, Status) {
                // alert(xData.responseXML.xml)
                $(xData.responseText).find("Version").each(function () {
                    preventiveListTemp.push({
                        "Description": $(this).attr("PreventionDescription"),
                        "Editor": $(this).attr("Editor").split(",#")[4],
                        "Modified": $(this).attr("Modified"),
                        "Image": "/_layouts/15/userphoto.aspx?size=S&accountname=" + $(this).attr("Editor").split(",#")[3].toLowerCase().replace("@", "%40")
                    });
                });
            }
        });

var filePath = '/sites/dk/sites/Departments/qms/Lists/Deviations/' + DID + '_.000'
var clientContext = new SP.ClientContext;
//var oList = clientContext.get_web().get_lists().getByTitle('Deviations');
var web = clientContext.get_web();
var listItemInfo = web.getFileByServerRelativeUrl(filePath);
var listItemFields = listItemInfo.get_listItemAllFields();
clientContext.load(web);
clientContext.load(listItemInfo);
clientContext.load(listItemFields);
clientContext.executeQueryAsync(function (sender, args) {
    var fileVersions = listItemInfo.get_versions();
    clientContext.load(fileVersions);
    clientContext.executeQueryAsync(function (sender, args) {
        var fieldEnumerator = fileVersions.getEnumerator();
        while (fieldEnumerator.moveNext()) {
            var oListItemVersion = fieldEnumerator.get_current();

            // preventiveListTemp.push({

            // });
