Top data structures a full stack developer must know

A full stack developer can work on a website from start to finish. They are also familiar with all aspects of web development, from coding and design to server administration and database management. 

To be a successful full stack developer, you must be familiar with various data structures. This blog post will discuss the top data structures that every full stack developer should know!

Data structures are the foundation on which algorithms are built. By understanding common data structures and their algorithms, you can optimize your code for better performance and readability. 

Nearly all software systems and programs that have been created use data structures. Data structures also fall under the umbrella of computer science and software engineering fundamentals. When it comes to interviewing questions for software engineering, it is a crucial subject.

Here are a few essential data structures every full stack developer should know:

1. Stack

Stack is a data structure that stores data in a Last-In-First-Out (LIFO) order. The most recently added data is the first to be removed. A stack gets often implemented using an array or a linked list. Because it resembles a stack of plates in the real world, this structure is called a "stack."

2. Queue

A queue is a data structure that stores data in a First-In-First-Out (FIFO) order. The longest data in the queue is the first to be removed. A queue gets often implemented using an array or a linked list. Because it resembles a real-world queue—a line of people waiting—this structure is called a "queue."

3. Heap 

A heap is a data structure that stores data in a way that allows quick retrieval of the minimum or maximum value. The parent nodes of a binary tree are compared to their children's values and arranged in a heap in this manner.

4. Hash table

It stores data in an associative array, a data structure that maps keys to values. Furthermore, if we know the key connected to the value, it supports lookup effectively.

5. Tree

This is a data structure that stores data in a hierarchical order. That is, each piece of data has a parent and zero or more child pieces of data. In contrast to a linked list, which linearly links items, this structure does not.

Over the years, different tree types have suited various applications and adhere to various restrictions. Binary search trees, B trees, treap, red-black trees, splay trees, AVL trees, and n-ary trees are a few examples.

Understanding these essential data structures allows you to optimize your code and make it more efficient. In addition, you will also be able to understand better the algorithms built on these data structures.
