Because declare return type of changeTitle() is string

What string is it returning? What is the meaning of the returned string?

[waitingsong]

It should return new title string , but not implemeted yet ....

    else {
      // const tt = getTitle(handle)
      return ''
    }

What would be the point of returning the value of a setter? I think setters should always return nothing or maybe success/failure if applicable. Or are you referencing something?

[waitingsong]

The new title may not equal to the input value completely, due to length, case or some thing others. Then developer can validate action result strictly, not only title write.

I see. If it was my library, I would offer a getTitle but its not, go for it. :sweat_smile:
