Immutability refers to the quality of something (like a variable or object) that cannot be modified after it has been created. It is used in programming to ensure data consistency, prevent unintended changes, improve concurrency by reducing lock contention, and simplify debugging because immutable objects don't need to be updated during their lifetime. In terms of codifying immutability, this can be achieved through the use of read-only variables or creating new objects when modifying data rather than updating existing ones.
