Tell us what’s happening:

Test 22 is failing. i dont know what to do. it says “dedupedFragments should have no duplicate id values”. please help

Your code so far

const shuffledFragments = [
  { id: 15, text: "and, after a time, passed the place where the Hare was sleeping." },
  { id: 12, text: "he lay down beside the course to take a nap" },
  ,
  { id: 11, text: "and to make the Tortoise feel very deeply how ridiculous it was for him to try a race with a Hare," },
  { id: 7, text: "but for the fun of the thing he agreed." },
  { id: 19, text: "The Hare now ran his swiftest," },
  ,
  { id: 1, text: "A Hare was making fun of the Tortoise one day for being so slow." },
  { id: 14, text: "The Tortoise meanwhile kept going slowly but steadily," },
  { id: 9, text: "marked the distance and started the runners off." },
  ,
  { id: 5, text: "I'll run you a race and prove it.\"" },
  { id: 17, text: "and when at last he did wake up," },

  ,
  { id: 13, text: "until the Tortoise should catch up." },
  { id: 10, text: "The Hare was soon far out of sight," },

it does not look like the variable exist yet, so any test about the variable fail by default

User story 7

You should declare a variable named dedupedFragments and assign it the result of calling dedupeFragments with the sortedFragments array.

oh sorry. thank you so muchhh. i was stuck. didnt read ahead.
