make a judgment first:

If the document only has one layer and the layer name is not aa.

I will rename this layer to "aa" and change the color to red

Correct answer rob day

var d = app.activeDocument;
if (d.layers.length == 1) {
    d.layers[0].properties = {name:"aa", layerColor:UIColors.RED}
}

Hi @rob day

How to determine if aa is at the lowest level (Location Options. AT-END)

Thank you very much.

The layer index goes from top to bottom, so the bottom layer is d.layers[d.layers.length-1]. You would use Location Options if you want to move a layer

var d = app.activeDocument;
//Bottom layer name
alert(d.layers[d.layers.length-1].name)
//Top layer name
alert(d.layers[0].name)
