| Argument | Type | Details | this: target | String | The string to search. |
pattern | String | The string to find. |
Examples
Code Editor (JavaScript)
print(ee.String('aBc-Abc').rindex('A')); // 4
print(ee.String('aBc-Abc').rindex('a')); // 0
print(ee.String('aBc-Abc').rindex('Bc')); // 1
print(ee.String('aBc-Abc').rindex('Z')); // -1
print(ee.String('aBc-Abc').rindex('-')); // 3
print(ee.String('aBc-Abc').rindex('')); // 7
Python setup
