ee.String.compareTo

  • compareTo lexicographically compares two strings, returning 0 if they are equal, -1 if the first string is less than the second, and 1 if the first string is greater than the second.

  • This method can be used on both client-side (JavaScript) and server-side (Python) Earth Engine environments and takes two string arguments for comparison.

  • The output is an Integer value (-1, 0, or 1) representing the comparison results.

 Compares two strings lexicographically. Returns: the value 0 if the two strings are lexicographically equal; -1 if string1 is less than string2; and 1 if string1 is lexicographically greater than string2.

Code Editor (JavaScript)

print(ee.String('a').compareTo('b'));  // -1
print(ee.String('a').compareTo('a'));  // 0
print(ee.String('b').compareTo('a'));  // 1

print(ee.String('a').compareTo(ee.String('b')));  // -1

Colab (Python)

print(ee.String('a').compareTo('b').getInfo())  # -1
print(ee.String('a').compareTo('a').getInfo())  # 0
print(ee.String('b').compareTo('a').getInfo())  # 1

print(ee.String('a').compareTo(ee.String('b')).getInfo())  # -1
