Author: Mutation of data types leaves a software developer in an interesting situation if the data was not formatted properly and thus could not be mutated. For example, the string “abc123” cannot be parsed into an integer. Many frameworks deal with this situation by immediately reporting an error condition. That error could be an exception that was thrown or a Boolean value of false to indicate failure. Keeping track of these states can easily introduce uncertainty into an application.
