In this course, you’ll study the fundamentals of JavaScript programming. You’ll begin by learning about basic data structures such as numbers and strings. This book starts with the fundamentals of the JavaScript language before moving on to the most significant data structures, such as arrays, queues, stacks, and linked lists. You’ll also obtain a thorough understanding of how hash tables and set data structures work. Following that, you’ll learn about trees and how to use the binary tree and binary search tree. Finally, advanced topics including efficient string search algorithms, caching algorithms, and dynamic programming difficulties are thoroughly discussed. You’ll use your newfound knowledge to create algorithms that manipulate strings, factorialize numbers, and even compute the orbit of the International Space Station once you’ve mastered the foundations.


Many beginners and expert programmers avoid learning Data Structures and Algorithms because they believe it is difficult and that they would never use it in real life. However, if you’re serious about yourself and your future, you’ll need to think about improving yourself in any way you can, and data structures and algorithms will help you a lot and put you ahead of the great majority of programmers. Arrays, stacks, queues, and other data structures will be used, as they are in every programming language. As a result, it is vital to be aware of it. A smart programmer can write an algorithm for any problem statement that is presented to them. Algorithms assist you in creating a sequence of steps to solve an issue. It is not required for you to master all of the algorithms available. If you have a thorough understanding of DSA, you will naturally develop the practice of writing optimized code. You’ll learn how to reduce the complexity of your code by developing the necessary abilities. In general, software development necessitates continual learning of new technology. If you don’t understand algorithms, you won’t be able to tell if the code you’re developing now can be optimized. You must know them ahead of time and implement them whenever possible and necessary. We talked about algorithm scalability in particular. Many of these algorithms make up a software system. Any one of them can be improved to make the system better.

Efficiency is critical for tackling coding challenges, from the number of coding hours to the amount of memory committed to a solution. Thankfully, JavaScript programmers make use of a variety of pre-built data structures that are designed to meet common needs and address real-world challenges. The ability to master data structures is a key differentiator between a new developer and a seasoned, hirable veteran. Understanding how data structures function and how to design algorithms to build applications is critical for JavaScript developers. Most data structure algorithms can be easily executed with JavaScript, a client-side programming language. Basic programming skills, such as dealing with variables, arrays, objects, loops, and functions, can then be turned into algorithms, allowing programmers to manipulate strings, factorialize numbers, and do sophisticated calculations. Understanding data structures, whether or not you utilize them in your day-to-day duties, is critical because it opens your eyes to patterns you’re currently dealing with but aren’t aware of.

The following is a list of the topics you covered in this course:

  • The big O Notation Algorithm is the subject of the first chapter. In this lesson, we’ll go through the big O Notation Algorithm in depth.

  • We learn about JavaScript scope, JavaScript integers, JavaScript strings, JavaScript arrays, and JavaScript objects in the second to sixth chapters.

  • The next chapter discusses memory management in Python. We study memory management in Python in depth.

  • We learn about searching and sorting, hash tables, stacks and queues, linked lists, cashing, Trees, heaps, and graphs from chapter ten to sixteen.

  • We learn about bit manipulation and dynamic programming in the last chapters.
