Can script read the properties of a Content Editor Web Part?

Question

I am working on a script, it's in AngularJS, but it could be jQuery or just JavaScript for the sake of this question. The script is inside a Content Editor Web Part. I want to provide configuration data to the script so it can be reused easily. In this particular case, I want to search and display the contents of a SharePoint List, but I don't want to hard-code the name of the List in the script.

When I was working with C#, I could easily modify the Properties pane. But for this assignment, I am working with script. I know the script is aware of of the URL, and I could pass the List name with a query string. But I am looking for a way to read a property from the Content Editor Web Part. Is that possible?

UPDATE: To make myself more clear, I want a reusable script I can put in ten different Web Parts. In each one of those Web Parts, I want to set a property of the Web Part that the script reads. So, WITHOUT rewriting the script, I configure it to read a different list in each Web Part.

You can use below code to get the webpart titles from the current page

var ctx = new SP.ClientContext();
var page = ctx.get_web().getFileByServerRelativeUrl('/sites/dev/SitePages/Home.aspx');
var wm = page.getLimitedWebPartManager(SP.WebParts.PersonalizationScope.shared);
var webparts = wm.get_webParts();
ctx.load(webparts,'Include(WebPart)');
ctx.executeQueryAsync(
    function () {
        for(var i = 0;i < webparts.get_count();i++) {
           var webpart = webparts.getItemAtIndex(i);
           var webPart = webparts.get_webPart();
           alert(webpart.get_title());
        }
    },
    function(sender,args){
        console.log(args.get_message());
    }
);
