A user-defined exception is thrown by the throw statement. The current function's execution will halt (the statements after throw will not be performed), and control will be passed to the call stack's first catch block. The program will end if no catch block exists among caller functions.

The throw statement, on the other hand, can be used to pass user-defined exceptions. The throw statement in JavaScript is used to handle user-defined exceptions. For instance, if a number is divided by 0 and you need to handle Infinity as an exception, you can use the toss statement.

Exceptions are raised by throws. An exception will be sent backwards via the stack to the function until it is captured by a catch block.
