We know about variable right? Now we are going to learn about data structures.
In computer science, a data structure is a data organization, management, and storage format that enables efficient access and modification. More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data. [wikipedia]

If you give a value which is more than index value then it will give you undefined –

Do you understand the Array ?
