Get anywhere within farming range, the two of them tower-dive you and then kick you while you're down in real life for trying to play. Yasuo dashes like crazy at you, or J4 combos to you, and you instantly die, no counterplay PERIOD.
I'm guessing you're not even supposed to lane against them, but what happens when they lane-chase you?
EDIT: For more context, my support was Taric.
Leti the Yeti1 votesyou're ashe dood you got crazy AA range, you got this you also need a good support cuz you're slow as fuq or else they will wreck you
darkdill1 votesWrong. Ashe's range doesn't do anything against J4's dive, which has more range. And Taric isn't exactly someone who can stop both of them at the same time.
Leti the Yeti1 votesget a decent morgana/janna/leona and you'll be fine you did not state your support was taric anywhere
so wat if jarvan has a long range engage? its not like thats not something we'v never seen before bot lane and all the adcs didnt just drop dead ;l
Anomander1 votesTry 
and
then the game becomes grab cho a bite to eat
Shadow Gilgamesh1 votesTry to get your jungler to let you take Gromp or Krugs, try lane switching, and farm under tower while saving your W for when they dive at you. Also a support with a hard CC like Leona or Morg would help, though if you don't have one there's not a whole lot you can do about that once the game starts.
Other than that, clench your butt and hope to last through laning.
Talamare1 votesAshe is one of the best counters for this lane, just need to W farm
Taric should help you farm
darkdill1 votesSo you want me to only farm with W and mana-burn every two minutes? Ashe doesn't exactly regenerate mana well.
Blastermine1 votesAshe kinda sorta gets hard countered by J4 in lane. only issue is that Yasuo is pretty useless as a support. So that why you go with the Jarvan Zyra lane!
darkdill1 votesJ4 was the support, Yasuo was the carry. Once they hit 6, you are guaranteed to die if you get within 800 range of them.
SmokingPuffin1 votesWell, a 1v2 lane is obviously pretty bad for the 1. If Ashe has a reasonable support, say a Janna or a Thresh, this game is easy to win.
You have a huge advantage level 1. You use it to get level 2 first. You shove the wave into the tower, then you base, get a Tear, and just farm safely. Come teamfight time, you easily siege turrets with W spam and generate picks with R.
