Algorithms and Data Structures

Understanding data structures and algorithms allows you to write more efficient code, correctly build the architecture of the project and individual modules.

Required knowledge: JavaScript

Flexible timing: start now and move comfortably

The course will help you gain a sought-after skill and increase your value as a specialist

Through the proper use of algorithms and data structures, you will be able to:

Correctly organize data for a specific task

Successfully pass interviews in large product companies

Solve more complex problems

Write code that runs faster and better

Algorithms and Data Structures
on the Competence Map of a Front-End developer

According to our Competency Map, understanding algorithms and data structures is an essential skill for developers with 1 to 3 years of experience.

After three years of experience, this knowledge becomes a necessity.

Typical problems that you will learn to solve using the right algorithms and data structures

You will learn how to choose algorithms and data structures for a specific task, and you will also be able to more effectively interact with data: search, filter and store in the correct format. This will help you solve problems such as:

Traversing trees to understand how templating engines work

Reviewer selection algorithm in pull request

Duplicate filtering for 100,000 positions

Data parsing

Storing and displaying alerts for the user

And many other tasks

How is the course going?

The course involves self-study of the material in a comfortable mode for you. You can start learning right now.

The program is divided into modules, each of which allows you to gradually master the skill from simple basics to complex subtleties.

Each module consists of:


Structured information needed to master a part of a skill


Examples of solving typical problems that will allow you to understand how theory turns into real practice

Practical task

For self-consolidation of the received theory. For each task, after completing it, you will receive a step-by-step solution to compare it with your own and make sure that it was completed correctly


For the final fixing of the material. It will allow you to make sure that you have learned everything exactly and you can move on.

To developers from developers

Made for developers who have little time to learn. On each course you will receive:


Links theory to typical tasks in the market. You will have an understanding of where and how to apply the resulting theory.


Built from simple to complex. You can easily immerse yourself in the topic, even if you didn’t know anything about it before.


Up-to-date and updated theory, tested by the market. No "water" - you will receive only the necessary knowledge.


Created around each course. It will help you answer questions and deepen your knowledge.

The community of each course consists of authors, experienced developers, and students who have taken or are taking this course.
The community not only helps in mastering the material, but also constantly makes the course better.

It suits you if:

You want to earn more or change jobs, but you don’t know in which direction to develop.

You want to learn a specific skill but don't know how

You do not want to waste time searching for relevant information on the topic

You need a specific teaching methodology and only the necessary information

You want to make sure that the acquired knowledge is learned in practice

We have experience, research and methodology on our side

An experience

We have been building a relationship with the commercial development market for 9 years. We train beginner developers and see how they become experienced specialists.


Before launching a course, we make sure that it provides a sought-after professional skill.


We communicate with the web developer community and therefore understand how to teach. We minimize the time from studying the theory to solving typical problems.
