Mutable or Immutable?

It is necessary to understand that there are mutable and immutable data types. The first one can be changed after its creation, but the second one prohibits us from making any modifications.

Immutable data types, as the name implies, cannot be changed once they're made.
In contrast, mutable data types are objects that can be altered after they're created.
