How do I convert the Uint8Array type to the string or hexadecimal type? How do I perform Base64 encoding? What are the differences between object assignment and deep/shallow copy? How do I implement shallow copy and deep copy? Does ArkTS support inheritance? Does ArkTS support inter...

A value of the collection type defined by TYPE t1 IS TABLE OF int cannot be assigned to t2, and vice versa. (This restriction may not take effect when the variables are of the member types because the value assignment logic of variables is affected by the parent type.) Only the equal ...
6.3.4 Delegate Instance Construction When a delegate type that has a compatibility value other than AtomicUncheckedis constructed from a method we make sure that the assignment is valid such that the delegate could be invoked safely without breaking the assumptions of both the caller and callee. ...

The assignment has the lowest priority. The expression above will first add b and c, and then write the result of this expression to the variable a. As a consequence of the previous remark, the value of a variable can be used in an expression, and then the result can be written into...
