--- id: 56bbb991ad1ed5201cd392ca title: Access Array Data with Indexes challengeType: 1 videoUrl: 'https://scrimba.com/c/cBZQbTz' forumTopicId: 16158 --- ## Description
We can access the data inside arrays using indexes. 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 zero-based indexing, so the first element in an array is element 0.
Example ```js var array = [50,60,70]; array[0]; // equals 50 var data = array[1]; // equals 60 ``` Note
There shouldn't be any spaces between the array name and the square brackets, like array [0]. Although JavaScript is able to process this correctly, this may confuse other programmers reading your code.
## Instructions
Create a variable called myData and set it to equal the first value of myArray using bracket notation.
## Tests
```yml tests: - text: The variable myData should equal the first value of myArray. testString: assert((function(){if(typeof myArray !== 'undefined' && typeof myData !== 'undefined' && myArray[0] === myData){return true;}else{return false;}})()); - text: The data in variable myArray should be accessed using bracket notation. testString: assert((function(){if(code.match(/\s*=\s*myArray\[0\]/g)){return true;}else{return false;}})()); ```
## Challenge Seed
```js // Example var ourArray = [50,60,70]; var ourData = ourArray[0]; // equals 50 // Setup var myArray = [50,60,70]; // Only change code below this line. ```
### After Test
```js if(typeof myArray !== "undefined" && typeof myData !== "undefined"){(function(y,z){return 'myArray = ' + JSON.stringify(y) + ', myData = ' + JSON.stringify(z);})(myArray, myData);} ```
## Solution
```js var myArray = [50,60,70]; var myData = myArray[0]; ```
