CreateCloudExpression[value]
creates a new anonymous cloud expression that stores the specified initial value.
CreateCloudExpression[value,"name"]
creates a new cloud expression with the specified name.
Details and Options

- The following options can be given:
-

PartProtection (2)
Create a cloud expression with no part protection:
expr = CreateCloudExpression[<|"a" -> {1, 2, 3}|>, "unprotected", PartProtection -> None]Change part of the expression, destroying its structure:
expr["a"] = None;Read the new value of the expression:
Get[expr]Get the part protection value:
Options[expr, PartProtection]Create a part protected cloud expression:
expr = CreateCloudExpression[<|"a" -> 1, "b" -> 2|>, "partprotected", PartProtection -> All]Attempt to modify the key "a", whose value is an integer:
expr["a"] = NoneRead the value associated to key "a"; it is unchanged:
expr["a"]Get the part protection value:
