Five Ways to Lazy Load Images for Better Website Performance

Lazy loading images can improve website performance by loading images asynchronously. Images have become one of the most used types of content in modern web applications. Although using background images improves the application’s look and feel, increasing image sizes can significantly impact application performance.   Even when properly optimized, images can weigh quite a bit and keep users waiting to access content on your website. Often, they get impatient and navigate somewhere else unless you come up with a solution to image loading that doesn’t interfere with the perception of speed. In this article, you’ll learn about five approaches to lazy loading […]

The real answer is, it depends. If you’re using TypeScript with React, pondering whether to use “type” or “interface” to define your prop types, you’re not alone. Both have unique advantages and applications in the ever-evolving landscape of React development. […]

Cookies vs. Local Storage vs. Session Storage: What’s the difference?

Cookies, Local Storage, and Session Storage are the storage methods in javascript. We’ll take a look at some examples and explore their differences.
