What is the syntax for layer-add-result in the map object?

A lot of the events for the map don't have any input parameters, but it looks like layer-add-result does. In the documentation, it says that the layer-add-result fires when you add the specified layer. But what is the syntax for this? I want to be able to see specifically when a particular layer is added, not just the plural version, layers-add-result.

The 'layer-add-result' event actually returns the layer that was added to the map in the callback.

You would have to check in the callback which layer was added and then do something based on that.

    on(map, "layer-add-result", function(layerAdded, errorMsg){                if(layerAdded.layer === myLayer){             console.log('found the layer i want, do something specific');            }     });

Just what I needed! Thanks for that.
