How would you remove a key from an object in Avaloq Script?

To remove a key from an object in Avaloq Script, using the delete keyword is the correct approach. The delete keyword specifically instructs the interpreter to remove a property or key from an object, effectively reducing the size of that object and freeing up resources. This operation not only removes the key but also ensures that any associated values are discarded, so they no longer consume memory.

The other options, while they may seem plausible, do not perform the intended operation in Avaloq Script. For instance, remove and unset are not recognized as valid commands for this purpose in the language. Similarly, the keyword free does not apply in this context, as it is typically used for memory management rather than for the manipulation of object properties. Thus, using delete is the appropriate and effective method to achieve the desired result of removing a key from an object.
