It _can_ be more performant because computers are exceedingly fast at cranking through arrays, especially if you can leverage SIMD, but its not just that. It's useful to play around with an array language until the paradigm clicks. Often, imperative code can be better handled in an array style. Sometimes long, fiddly functions can be greatly simplified if you use array operations instead or in conjunction with other styles.
