Basic JavaScript - Using Objects for Lookups

JavaScript

Tell us what’s happening:
Hey everybody! Can you spot the mistake?

Your code so far

// Setup
function phoneticLookup(val) {
  let result = "";

  // Only change code below this line
  const lookup = {
    "alpha": "Adams",
    "bravo": "Boston",
    "charlie": "Chicago",
    "delta": "Denver",
    "echo": "Easy",
    "foxtrot": "Frank"
  };

  const lookup = result;

  // Only change code above this line
  return result;
}

phoneticLookup("charlie");

What is this line doing?

3

Good question

I thought it could be used to output result.

4

That line says, “declare a brand new variable called lookup and put the current value stored in the variable called result into this new variable called lookup”

5

hmm… then that’s not the output I am looking for.

Can you give me a hint of change?

const articleAuthor = article["author"];
const articleLink = article["link"];

const value = "title";
const valueLookup = article[value];

This was the example in the Challenge, so you probably need something that looks like that?

You want to update the result with the values given in the lookup and the val.
