if
Executes a given block of code if the value of this nullable type is not null. This function allows for safe, chained operations on a nullable object, similar to let, but it returns the original receiver (this) instead of the result of the lambda. This is useful for performing side effects on a non-null value without altering the flow.
Return
The original nullable object, allowing for further chaining.
Parameters
action
The block of code to execute, which receives the non-null value as its argument.
Type Parameters
T
The type of the value.
