Examples
Code Editor (JavaScript)
// Element-wise boolean "and" operator.
// Both arrays must be the same dimensions.
var arrayNeither = ee.Array([0, 0]);
var arrayFirst = ee.Array([1, 0]);
var arraySecond = ee.Array([0, 1]);
var arrayBoth = ee.Array([1, 1]);
// Any non-zero value is true.
var arrayLarger = ee.Array([-2, 2]);
print(arrayBoth.and(arrayLarger)); // [1, 1]
print(arrayBoth.and(arrayNeither)); // [0, 0]
print(arrayFirst.and(arraySecond)); // [0, 0]
print(arraySecond.and(arrayFirst)); // [0, 0]
print(arrayBoth.and(arrayFirst)); // [1, 0]
print(arrayBoth.and(arraySecond)); // [0, 1]
print(arrayNeither.and(arrayFirst)); // [0, 0]
print(arrayNeither.and(arraySecond)); // [0, 0]
// Works the same for all PixelTypes.
var arrayDouble = ee.Array([0.0, 2.0], ee.PixelType.double());
print(arrayBoth.and(arrayDouble)); // [0, 1]
