In JavaScript, objects are stored as key value pairs. This is an example of inbuilt hash table in the language itself. If you want to customize hash table and create your own you can. Hash tables can be implemented as a linear or non-linear data structure. …

In this article, let us see how Graph data structure works. Graphs are non-linear data structure like trees. Graphs consists of vertex (or node) and edge (or arrows or connection). When they are connected they form a network which can be in one direction or both direction. Graphs are used…

In previous articles, I wrote about various linear data structures such as Arrays Linked Lists and Stacks Now lets us look into another linear data structure called “Queue data structure”. Queues are very similar to like Stacks which is similar to Linked list. …

I wrote about linear data structures such as Arrays and Linked list(LL) previously. Now, let us look into Stacks which is also a linear data structure and is very similar to LL. A Stack is a collection of items that can only be stored or deleted in a particular order…

In the previous article, we saw how linked list data structure works. Let us discuss “Trees” data structure in this one. Trees are used to store non linear hierarchical data such as an organization chart in a company. You can consider a linked list as a form of a tree…

In my previous article, I mentioned about Array Data Structure. Like Arrays, Linked List are also another way to structure, manage and organize data. In order to understand linked list(LL) let’s compare it to Arrays. …

Why writing your goals are so important? I have been writing my yearly goals every December. For the past 5 years, it has made a lot of difference in my life. This year I have met almost all my goals and have done few things beyond my goals too. I write only 10 goals for the entire…

In my previous article, I mentioned that algorithms are steps performed on some data to solve some problem(s). Data structures are ways we structure, manage and organize data. For example, If you want to sort the videos in YouTube, we click the sort icon to sort. How does it sort…

You must have heard about Big O notation when you started learning to code. This buzzword is all over the place and is initially confusing. Ask yourself, how does Google search work? How do you get the search results listed based on relevancy? This depends on the algorithm used. …
