Selects one of its inputs based on a condition, similar to an if-then-else construct.

ee.Algorithms.If(condition, trueCase, falseCase)Object
conditionObject, default: nullThe condition that determines which result is returned. If this is not a boolean, it is interpreted as a boolean by the following rules:   - Numbers that are equal to 0 or a NaN are false.   - Empty strings, lists and dictionaries are false.   - Null is false.   - Everything else is true.
trueCaseObject, default: nullThe result to return if the condition is true.
falseCaseObject, default: nullThe result to return if the condition is false.

print(ee.Algorithms.If(false, '*true*', '*false*'));  // The string "*false*"
print(ee.Algorithms.If(true, '*true*', '*false*'));  // The string "*true*"

// Consider using remap rather than If for tasks like numbers for classes.
print(ee.Algorithms.If(ee.String('Tree').compareTo('Tree'), 0, 1));
print(ee.Algorithms.If(ee.String('NotTree').compareTo('Tree'), 0, 1));
