Hardening your servers not only makes them more resilient but also forces attackers to either move on or, ideally, abandon their efforts altog

How I Run JavaScript in VS Code

by: Abhishek Kumar Sat, 31 May 2025 04:29:37 GMT In one of my earlier articles, I showed how you can preview HTML files inside Visual Studio Code. That setup worked well for testing static pages, but what if you want to go beyond markup and bring interactivity into the mix? With JavaScript being the backbone of the modern web and countless developers now diving into frameworks like React, Vue, and Svelte, being able to run JavaScript code directly inside VS Code becomes almost essential.
