JSON.DEL
Syntax
JSON.DEL key [path]
Time complexity: O(N) when path is evaluated to a single value where N is the size of the deleted value, O(N) when path is evaluated to multiple values, where N is the size of the key
Delete a value
Required arguments
key
is key to modify.
Optional arguments

Note
Deleting an object's root is equivalent to deleting the key from Redis.
