JavaScript: I'm trying to change this string into an array. What is wrong with my code?

      localStorage.setItem("savedItems", `[{name:\"Marcus\", select:\"going\", notes:\"Filler text.\"},
                                           {name:\"Tom\", select:\"not going\", notes:\"Has a business meeting so he can't come.\"}]`);

      const inviteList = localStorage;

      const get = inviteList['savedItems'];
      const getArray = JSON.parse(get);

This is the full error that I get:

Uncaught SyntaxError: Unexpected token n in JSON at position 2

Keys in JSON objects must be in quotes, unlike in JavaScript where keys can be in quotes or not. So it's trying to parse this: [{name: ... and it's running into a problem at the letter n because it doesn't know how to handle the letter n in this context. It should be like this instead: [{"name":...

I'm also not sure why you would be needing to pass in a string object hard coded like this in the first place. If you have a JavaScript object, you could convert it to a string with JSON.stringify() and it would automatically take care of converting it to the right format, with object keys wrapped in quotes. Also, FYI, you're escaping all your quote characters (\") but this is unnecessary in this case because the whole thing is a template string wrapped in back ticks (`)
