 ```js
 const array = [50, 60, 70];
-array[0];
+console.log(array[0]);
 const data = array[1];
 ```
 
-`array[0]` is now `50`, and `data` has the value `60`.
+The `console.log(array[0])` prints `50`, and `data` has the value `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.
