Webpack
Webpack is a popular tool that helps web developers organize and combine their website files efficiently. Think of it like a smart packaging system that takes all the different pieces of a website (like code, images, and styles) and bundles them together in the best way possible. This makes websites load faster and work better. It's particularly important for modern websites that use frameworks like React or Angular. When you see Webpack mentioned in a resume, it usually means the candidate knows how to properly organize and optimize web projects.
