Array Data Structure | Illustrated Data Structures

An array is a collection of items where items are stored consecutively. In this video, we will discuss everything you need to know about the array data structure. We start with the introduction to the array data structure, then we discuss how they work in memory. We learn the limitations and see an example of arrays in languages such as C++; after that, we see how the languages such as JavaScript, PHP, or Ruby implement the arrays to go around the limitations of fixed size and single type array values, and then finally we learn about the different operations you can perform on arrays along with the algorithmic complexity.

After watching this video, you will be able to answer the following questions:

- What are arrays?
- How do the arrays work?
- What are some of the limitations of arrays?
- How can languages such as JavaScript have dynamically sized arrays and mixed-type values?
- What are some of the operations you can perform on an array?
- What is the algorithmic complexity of those operations?

Some minor corrections:

- 01:35 fourth element will be numbers[3] because arrays are 0 indexed
- 08:13 It's the 6th element and not the 5th

Now I understand how JavaScript allocates more memory for mixed types. Awesome and very well explained. Thanks for this video. ❤❤

This easy and effective teaching style can even make a non-computer science student understand these things quite easily.

This deserve to be in trending topic to IT students.

Very concisely explained, great stuff!

One of the best video on Arrays. I was working in JavaScript but did not know how JavaScript handle mixed type and dynamic size. Thank you Kamran.

2:02 it actually allocates four slots in memory. One represented by numbers[3] and then three for the three values 10, 59, and 11.

Man you're so underrated. Nice tuts!

[dubrbro]

Perfect, thank you for what you're doing!

Sir please make a roadmap video on Frontend Webdevlopment from beginners to Advance.

Accessing out of bound value of array, gives us a garbage value (c++), so that garbage value is from any other program/software, or its just randomized value given by compiler???

Thanks bro. Your vidoes are so perfect!!!
