javascript - Difference between done() vs spread() of bluebird -

hi not getting difference of spread() vs done() of bluebird library of javascript.even bluebird wrapper of q q has both functions in it's library.

can explain me difference between both of these functions?

thanks in advance !

even bluebird wrapper of q so…

oh, not. hope doesn't invalidate question?

i not getting difference of spread() vs done()?

the api docs might lot:

• spread "like calling .then, fulfillment value or rejection reason must array, flattened formal parameters of handlers."

  if have promise array, spread call callbacks multiple arguments.

  it's same q does: spread "like then, "spreads" array variadic fulfillment handler."

• done "like .then(), unhandled rejection ends here thrown error. [… it] used explicitly mark end of promise chain."

  more details on can found in error handling documentation. notice bluebird quite different q here, smartly figures out unhandled rejection , reports them on own - don't have explicitly tell throw global error when rejection got point.

  compare q's done documentation, recommends unconfined use.

as can see, spread , done different methods different purposes. also, done patterns differ between bluebird , q.
