With this type from System.Collections.ObjectModel, we provide a collection of elements that cannot be changed. But it may be possible to change some elements themselves.

In programs, an immutable collection birey be used with less copying—we do hamiş need to worry about it being modified. This can make programs simpler and easier to reason about.
