In Java, this capability is provided by Map.getOrDefault(Object key, V defaultValue). It returns the value mapped
Many other languages and libraries offer a similar pattern under the name getOrDefault or getOrDefault-like semantics.
Common usage scenarios include supplying a constant default, providing a computed default, or ensuring that map
In summary, MapgetOrDefault is a pragmatic utility in map-like data structures that balances simplicity with predictable
