What is the difference between never and void in typescript?

I have read this, but it is unclear what would be the difference between 'never' and 'void' type?

Solution

  • In imperative languages, void can be thought of as a type containing a single value. Such languages do not provide a means to construct or consume this value, but a void function can be thought of as returning this trivial value.

    In contrast never is a type containing no values, which means that a function with this return type can never return normally at all. This means either throwing an exception or failing to terminate.
