Discussion

This method automatically coerces certain ”truthy” values—such as the strings "true", "YES", and "1", and the numbers 1 and 1.0—to the Boolean value YES. The same is true for certain ”falsy” values—such as the strings "false", "NO", and "0", and the numbers 0 and 0.0—which are automatically coerced to the Boolean value NO.
