Immutable List
An Immutable List is a data structure that cannot be changed after it is created. This means that once you add elements to the list, you cannot modify, remove, or reorder them. Immutable lists are often used in programming to ensure data integrity and prevent accidental changes, making them useful in functional programming languages like Haskell or Scala.
In contrast to mutable lists, which allow for modifications, immutable lists provide benefits such as easier debugging and improved performance in certain scenarios. They can also help with concurrency, as multiple threads can safely access the same list without the risk of one thread altering it while another is reading it.
