title: Access Array Data with Indexes

# --description--

We can access the data inside arrays using <dfn>indexes</dfn>.

Array indexes are written in the same bracket notation that strings use, except that instead of specifying a character, they are specifying an entry in the array. Like strings, arrays use <dfn>zero-based</dfn> indexing, so the first element in an array has an index of `0`.

<br>

**Example**

```js
const array = [50, 60, 70];
console.log(array[0]);
const data = array[1];
```

The `console.log(array[0])` prints `50`, and `data` has the value `60`.

# --instructions--

Create a variable called `myData` and set it to equal the first value of `myArray` using bracket notation.

# --hints--

The variable `myData` should equal the first value of `myArray`.

```js
assert(
  (function () {
    if (
      typeof myArray !== 'undefined' &&
      typeof myData !== 'undefined' &&
      myArray[0] === myData
    ) {
      return true;
    } else {
      return false;
    }
  })()
);
```

The data in variable `myArray` should be accessed using bracket notation.

```js
assert(
  (function () {
    if (__helpers.removeJSComments(code).match(/\s*=\s*myArray\[0\]/g)) {
      return true;
    } else {
      return false;
    }
  })()
);
```

# --seed--

## --seed-contents--

```js
const myArray = [50, 60, 70];


```

# --solutions--

```js
const myArray = [50, 60, 70];
const myData = myArray[0];
```
