Lagging object renaming

The name property contains the name of the objects in Illustrator, which is displayed in the Layers panel. To rename a selected object, just use this construction:

selection[0].name = "square";

In Illustrator older than CC 2020 we are in for a surprise, the new name will not appear in the Layers panel until we reset the selection or select another object.

The new name is displayed only after the action

Solution
A quick way to see the new name and have the object remain selected is to re-open the Layers panel after renaming it.

app.executeMenuCommand("AdobeLayerPalette1"); 
redraw();
app.executeMenuCommand("AdobeLayerPalette1");

And these lines can be wrapped in a function to be called quickly, as I did in my RenameItems script.

selection[0].name = "square";
reopenLayersPanel();
function reopenLayersPanel() { 
  app.executeMenuCommand("AdobeLayerPalette1"); 
  redraw();
  app.executeMenuCommand("AdobeLayerPalette1");
}

The new name of the selected object immediately appears in the Layers panel
