var dict = {
  B1: 182,
  B2: 219,
  B3: 443
};
print('ee.Dictionary from dictionary input', ee.Dictionary(dict));

// A list of key/value pairs (from previous dictionary).
var list = [
  'B1', 182,
  'B2', 219,
  'B3', 443
];
print('ee.Dictionary from list input', ee.Dictionary(list));

// To create an ee.Dictionary from two corresponding lists of keys and values,
// use the ee.Dictionary.fromLists constructor.
var keys = ['B1', 'B2', 'B3'];
var values = [182, 219, 443];
print('Dictionary from lists of keys and values',
      ee.Dictionary.fromLists(keys, values));
