Question: I don't know why my **findDroids** function cannot reference the *result* variable within my **droids** function. When I run this code, I get "result is not defined". Any tips/guidance is greatly appreciated. I'm new to Javascript, so please go easy on me :)

```
function droids(arr) {
  let result = '';
  arr.forEach(findDroids);
  return result;
}

function findDroids(value, index, arr){
  if (arr[index] == "Droids"){
    result = "Found Droids!";
  } else{
    result = "These are not the droids you're looking for."
  }
}

// Uncomment these to check your work! 
const starWars = ["Luke", "Finn", "Rey", "Kylo", "Droids"] 
const thrones = ["Jon", "Danny", "Tyrion", "The Mountain", "Cersei"] 
console.log(droids(starWars)) // should log: "Found Droids!"
console.log(droids(thrones)) //should log: "These are not the droids you're looking for."

```

Answer: 
Because in JS `let` variables are scoped to its nearest function. In this case `result` is only available at `droids` level. Making the variable global should work:

```js
let result = ''; // Available everywhere

function droids(arr) {
  //let result = ''; // Available only at `droids` level
  arr.forEach(findDroids);
  return result;
}

function findDroids(value, index, arr){
  if (arr[index] == "Droids"){
    result = "Found Droids!";
  } else{
    result = "These are not the droids you're looking for."
  }
}

// Uncomment these to check your work! 
const starWars = ["Luke", "Finn", "Rey", "Kylo", "Droids"] 
const thrones = ["Jon", "Danny", "Tyrion", "The Mountain", "Cersei"] 
console.log(droids(starWars)) // should log: "Found Droids!"
console.log(droids(thrones)) //should log: "These are not the droids you're looking for."
```

Having said that, using a global variable is probably not the best thing. You can find a `needle` in a `haystack` with `haystack.includes(needle)` to easily check if an array includes the value you are looking for:

```js
const arr = ["qqq", "www", "eee"]
console.log(arr.includes("qqq") ? "Found droids" : "Not found")
console.log(arr.includes("zzz") ? "Found droids" : "Not found")
```
```
function droids(arr) {
  return arr.some(function(a){return a === "Droids";});
}

```

The 'some' suggestion. Check other examples for 'includes', probably a better tool for the job.
