As in the Hillshade Example, I wanted to automate adding all Layer from one Image for visual inspection.

var band_names =Image.bandNames()
print(ee.String(band_names.get(0)))
  for (var i = 0; i < 4; i += 1) { 
  Map.addLayer(Image.select(ee.String(band_names.get(i))), {}, ee.String(band_names.get(i)));
}

This returns the longest Error ever, not gonna post it entirely enter image description here

2 Questions:

  1. the Layer name is a String:

    print(ee.String(band_names.get(0))) 
    

    yields a string. What's wrong with this code?

  2. How do I call the number of Bands for the automation? I imagine something like :

    ee.Number(ee.Image.bad
    
1

You can't use a computed object for the layer name, only literal strings. You can download all of the band names from the server into a list of strings using getInfo(), and then it would work.

var band_names = Image.bandNames().getInfo()
for (var i = 0; i < 4; i += 1) { 
    Map.addLayer(Image.select(band_names[i]), {}, band_names[i]);
}
