Sequential read/write operations involve accessing data in a continuous, linear manner. This typically occurs when transferring large files or accessing a large file on the drive. In sequential read/write operations, the drive can read or write data from a series of blocks, allowing for faster performance...

Sql and how it relates to disk reads and writes

A deep dive into the rendering process of a web page, exploring the Document Object Model (DOM), CSS Object Model (CSSOM), and the Render Tree.

From markup to pixels - a look inside the DOM, CSSOM, and render tree

Shadow DOM is a web standard that allows encapsulation of HTML, CSS, and JavaScript within a specific context.

Shadow DOM

Actually, the DOM is not slow. Adding or removing a DOM node is not much more than setting a property on the JS object. However, _layout_ is slow. Imagine adding a DOM node changes the height of the document, it would invoke a bunch of [rendering processes](https://web.dev/rendering-performance/) to redraw the screen. And all the complex algorithms behind the those processes makes any changes in DOM potentially expensive.

Why DOM manipulation is slow?

React and Vue, two popular front-end frameworks, both use Virtual DOM to improve page rendering efficiency. Understanding the concept of Virtual DOM sheds light on an important aspect of performance optimization on the client side.
