This seems very basic, but I cannot figure out how to extract the image names from an image collection in Google Earth Engine. I can get a count of the number of images, but not the names. Here is an example.
var ROI = ee.Geometry.Rectangle(-82.5574, 35.5958, -82.5563, 35.59515); // define area
var collection = ee.ImageCollection('LANDSAT/LC08/C01/T1')
.filterDate('2014-05-01', '2015-10-01')
.filterBounds(ROI);
Now I want to do something like collection.ImageNames().
