What is virtual scroll ? Virtual scroll (also called virtualization or windowing) is a technique used to efficiently render large lists in web applications — without loading everything into the DOM at once. Instead of rendering 1,000+ items, you only...
The graph data structure is a fundamental concept in computer science, and it is used in various domains such as social networks, transportation systems, and computer networks. A graph is a collection of nodes connected by edges, where each node repr...
So far we've looked at implementation of tree data structure and some of it's variants such as trie. In this post, we'll dive into heaps. These are also referred to as priority queues. Introduction Heap is a variant of tree data structure, with two a...
We've already covered the basics of tree data structure in three posts. If you haven't gone through those yet, I would strongly going through the introductory post at the very least. Introduction Trie is a variation of tree data structure. It's also ...
HTTP(Hyper Text Transfer Protocol) is one of many protocols used for transferring data (think of html pages, text, images, videos and much more) across machines. There are other application layer protocols like FTP, SMTP, DHCP etc. HTTP was invente...
What's a design pattern in software engineering? It's a general repeatable solution to a commonly occurring problem in software design. In this article, we'll be looking at one of such common design patterns and see how it can be put to use in real w...
We've looked through few binary tree traversal techniques so far: 1- Traversing through the binary tree using recursive and iterative algorithms 2- Traversing through the binary tree using parent pointers In this article, we'll put those learnings to...
Memoization is a useful concept. It helps avoid time taking or expensive calculations after it's been done once. Applying memoization to a synchronous function is relatively straightforward. This article aims to introduce the overall concept behind m...
In the first part of this series we looked at recursive and iterative approaches for traversing through a binary tree. If you haven't looked through it yet, I highly recommend you to check it out first. I'll wait here, I promise ;) In real life app...
