**What are data structures?**

Data structures are used to store data in an organized way, making data manipulation more efficient. They’re a collection of:

- data values
- relationships
- functions

These data structures help efficiently manage large amounts of data.

Some of the most popular data structures include:

arrays | linked lists |

stacks | queues |

hash tables | trees |

heaps | graphs |

That may not make much sense to you now, but it will after taking a course or two on data structures.

### And today we’re showing you the best data structures courses for this year.

So whether you learn best by doing, by video, or a mix of the two, we think there are data structures courses for just about everyone.

**2. Master the Coding Interview: Data Structures + Algorithms: Zero to Mastery**

**Zero to Mastery** is the platform created by renowned and beloved instructor Andrei Neagoie.

You might know him from his highly-acclaimed bootcamp-style course The Complete Web Developer: Zero to Mastery. ***insert fan girl scream here***

You’ll find that **Zero to Mastery** is much different than **Educative.io**. Instead of interactive learning, you’ll spend the majority of your time watching videos and then doing all work on your local machine instead of in the browser. In addition, you’ll find some downloadable readings.

💡 *Because videos contain text, moving images and sound, they encourage multi-sensory learning. This enables you to make cognitive connections and think more deeply.*

**Master the Coding Interview** touts itself as a coding interview bootcamp. So instead of going slow, you can expect a fast-paced, stimulating learning experience.

In addition to learning how implement and use different data structures and algorithms, you’ll learn how to ace the FAANG interview.

**Course Layout**

**Zero to Mastery** is a video-based platform where you’ll do all work outside of the browser. In **Master the Coding Interview**, you’ll be redirected to LeetCode to work on a few problems.

**Master the Coding Interview** is a massive course with 21 modules. However, 7 modules are dedicated exclusively to data structures.

After the introduction the data structures, you’ll learn about:

arrays | hash tables | linked lists |

stacks + queues | trees | graphs |

Each module contains a series of lessons where you’ll explore concepts and work on exercises.

For example, in **Arrays**, you’ll learn about static vs. dynamic arrays. Then you’ll discover implementing an array and more.

**Community**

**Zero to Mastery** has a bustling community on Discord and LinkedIn. You can also work on open source projects and check out their job board.

**3. Introduction to Data Structures: Treehouse**

**Treehouse** is similar to **Zero to Mastery** in that it’s a video-based course. But at only 2.75 hours, **Introduction to Data Structures** is much shorter than **Master the Coding Interview**.

**So if you have a short attention span, this might be the course for you.**

💡 *Short courses can be beneficial for “taste-testing” a career path. You can see if you find the material interesting. Then you can pursue more in-depth courses.*

**Introduction to Data Structures** focuses on two data structures: arrays and linked lists. Then you’ll merge data structures with algorithms to solve sorting data by using the merge sort algorithm.

**Course Layout**

**Treehouse** is a video-based platform where you’ll do all work outside of the platform on your local machine.

**Introduction to Data Structures** contains 4 action-packed modules:

- Exploring Arrays

**4. Linear Data Structures: Codecademy Pro**

**Codecademy Pro** is different than **Educative.io**, **Zero to Mastery** and **Treehouse**. They take a mash-up approach.

For example, in addition to **Codecademy Pro’s** interactive learning environment, you’ll find videos that introduce new concepts.

In **Linear Data Structures**, you’ll build fundamental data structures in computer science: lists, stacks and queues.

💡 *Linear data structures contain elements that are arranged sequentially. So one element is connected to the previous and next element.*

**Course Layout**

As we mentioned, **Codecademy Pro** uses a blend of interactive learning and videos to teach concepts. And like other interactive learning courses, you’ll do all work in the browser.

So there’s no need to set up your own developer environment.

You’ll learn data structures in **Linear Data Structures** with four modules:

- Learn Nodes
- Linked Lists
- Learn Stacks
- Learn Queues

Each module has two lessons and two multiple choice quizzes. But the module **Learn Stacks** has something the other’s don’t: **a project**.

In the project **Towers of Hanoi**, you’ll use what you’ve learned about stacks to move a stack of disks from from Point A to Point C. But it’s not as simple as it seems: You can never place a larger disk on top of a smaller disk. 🤔

**Community**

**Codecademy** has an active forum where you can get help from other students, share projects and more.

**💰 Cost:** $39.99 per month or $239.88 per year for **all courses** and Learning Paths
