I want to get something like this: oranges

However no output is displayed. I tried printing via console and it doesn't work. 

var array2 = ["Banana", ["Apples", ["Oranges"], "Blueberries"]];

    @JoshuaIbemgbo That's what you need to use, and it works... so what's the problem? – Rory McCrossan Aug 29 '18 at 13:38

Since the desired fruit resides inside into third level, you have to use 3 indexes. Try array2[1][1][0].

Step by step:

array2[1]        => ["Apples", ["Oranges"], "Blueberries"]
array2[1][1]     => ["Oranges"]
array2[1][1][0]  => Oranges


var array2 = ["Banana", ["Apples", ["Oranges"], "Blueberries"]];

console.log(array2[1][1][0]); // Oranges

you can use Destructuring assignment on your array

but that's seem like overkill here

var array2 = ["Banana", ["Apples", ["Oranges"], "Blueberries"]];

let [,[,[orange]]] = array2

console.log(orange)

I added this answer to inform this way existed, BUT the answer from @Mamum is the way to go to when you need to get a small number of values from an array :

let orange = array2[1][1][0]

Welcome Joshua!

Arrays are accessible starting from index 0, so in order to access the inside array ["Apples", ["Oranges"], "Blueberries"] you need to write array2[1] since it is the second item in the array.

Next you need to access the ["Oranges"] which is also the second item in that array, resulting in array2[1][1].

Finally since array2[1][1] also returns an array containing "Oranges" in its first index (0), you have to write array2[1][1][0] which will give you the result

console.log(array2[1][1][0])

Your arrays are currently nested, are you sure that's what you want? Since you have a pretty linear list of items here, I would suggest taking the internal arrays out:

var array2 = ["Banana", "Apples", "Oranges", "Blueberries"];

Array contents can be called by using the index number associated with the item you are trying to select. In this case:

console.log(array2[2]);

Here is the MDN documentation on JavaScript arrays, for your reference :)
