What programming languages support mutable data?
Languages like Python, Java, and JavaScript allow mutable data, enabling changes to data structures after creation.
Can you give examples of mutable data types in these languages?
Sure! In Python, lists and dictionaries are mutable. In Java, ArrayLists and HashMaps are examples. JavaScript has arrays and objects.
Why would I choose mutable data over immutable data?
Mutable data can be more efficient for certain operations, as it allows in-place modifications without creating new objects.
Are there any downsides to using mutable data?
Yes, mutable data can lead to unintended side effects and bugs, especially in concurrent programming, where data can be changed unexpectedly.
