ee.Date.aside

    • The aside method calls a function with the current object as the first argument and returns the object itself for chaining.

    • It is useful for debugging or adding intermediate steps like printing values or adding layers to a map during chained operations.

    • The aside method takes a function and optional additional arguments to pass to that function.

    • The method returns the same ComputedObject it was called on.

     Calls a function passing this object as the first argument, and returning itself. Convenient e.g. when debugging:

    var c = ee.ImageCollection('foo').aside(print)

    .filterDate('2001-01-01', '2002-01-01').aside(print, 'In 2001')

    .filterBounds(geom).aside(print, 'In region')

    .aside(Map.addLayer, {min: 0, max: 142}, 'Filtered')

    .select('a', 'b');

    Returns the same object, for chaining.
