# 6.3 Unwrap flavours

The other unwrap functions are all variations that exit the current control flow in a slightly different manner.

`unwrap!` takes an `optional` or `response` as the first input and a throw value as the second input. It follows the same unwrapping behaviour of `try!` , but instead of propagating the the `none` or the `err` it will return the the throw value instead.
