Tell us what’s happening:

I am unable to pass test 5. I’m trying to check if the parsed array from local storage 1. is an array and 2. if each object in the array has the three required properties. If it passes then I return the array. If it fails I return an empty array.

All the other tests pass, it’s just this one validation test.

Your code so far

const getBookmarks = () => {

  const bookmarksData = JSON.parse(localStorage.getItem("bookmarks"));

  if (Array.isArray(bookmarksData) && bookmarksData.every((object) => {
    return object.hasOwnProperty("name") && object.hasOwnProperty("category") && object.hasOwnProperty("url")
  })) {
    return bookmarksData
  }
  return [];

};

The problem is that JSON.parse() will crash your entire function if the data in localStorage isn’t valid JSON, so you need to wrap it in a try/catch block to catch the error and then return an empty array.
