Announcement: On November 13, 2024, all users will need to use a Cloud project in order to access Earth Engine. After this date, continued individual access without a Cloud project will require an exception.

ee.Date.aside

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.

Usage	Returns
`Date.aside(func, var_args)`	ComputedObject

Argument	Type	Details
this: `computedobject`	ComputedObject	The ComputedObject instance.
`func`	Function	The function to call.
`var_args`	VarArgs	Any extra arguments to pass to the function.

Examples

Code Editor (JavaScript)

// Print a message when constructing the ee.Date.
var eeDict = ee.Date(Date.now()).aside(print, "Today's date (UTC)");

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

from datetime import datetime

def print_date(ee_date, message):
  """Prints a formatted date, along with a descriptive message."""
  display(message, ee_date.format("YYYY-mm-dd"))

# Print a message when constructing the ee.Date.
ee_date = ee.Date(datetime.now()).aside(print_date, "Today's date (UTC):")
