How does Immutable.js ensure that data remains immutable?

  • By converting all data to primitive types.
  • By disallowing any updates or modifications to the data.
  • By creating copies of data objects whenever updates are made.
  • By using structural sharing and creating new objects for changes.
Immutable.js maintains data immutability by using structural sharing. When a change is made, a new object is created with the updated data, while the original data remains unchanged. This ensures immutability without the need for deep copying, making it more memory-efficient. The other options do not accurately describe how Immutable.js achieves data immutability.
