A data structure is a way to store and organize data so that it can be used efficiently.
A data structure is a collection of data values, the relationship among them, and the functions or operations that can be applied to data.
Almost every application we build involves data that is modelled in a certain way.
To efficiently manage that data, we need data structures
Imagine walking into a library only to find out there is no efficient organization of the books and they are stored randomly.
The difference between a function taking a few milliseconds vs a few seconds or even minutes comes down to the selection of the right data structure.
Data structures help you solve problems in a more efficient way, both in terms of time and memory.
Learning about data structures also help us gain a more profound understanding of things we are already aware of. - DOM: it uses the Tree and data structures - Browser back and forward: it uses the Stack data structure - OS job scheduling: it uses the Queue data structure.
In this series of Data structures we will learn about the various types of data structures such as built-in structures [Arrays, Objects, Sets, Maps] and Custom data structures [Stacks, Queues, Circular Queues, Linked list, Hash Table, Trees, Graphs].
