What is the meaning of the error message "deprecated name" and the expression expected with the code error ts(1109)?

edit

The error message "deprecated name" means that the code is using a name or identifier that is no longer recommended or supported by the current version of the programming language or framework. It may still work, but it is advised to switch to a newer, recommended alternative.

The error message "expression expected" with the code error ts(1109) means that something is missing in the code that is expected to provide a value or expression, such as a variable, function, or operator. This error often occurs when there is a missing parenthesis, bracket, or curly brace. It can also occur when there is a missing value or argument in a function call.
