קל לארגן דפים בעזרת אוספים
אפשר לשמור ולסווג תוכן על סמך ההעדפות שלך.
מפעילה פונקציה ומעבירה את האובייקט הזה כארגומנט הראשון, ומחזירה את עצמה. נוח, למשל, כשמבצעים ניפוי באגים:
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');
מחזירה את אותו אובייקט, לשרשור.
