npm
npm (Node Package Manager) is like a digital library system that software developers use to easily add pre-built components to their projects. Think of it as a massive collection of ready-made building blocks that developers can quickly install and use, rather than creating everything from scratch. It's primarily used with JavaScript, one of the most popular programming languages for websites and apps. When you see npm in a resume, it indicates the person knows how to efficiently manage and use these building blocks in their development work. This is similar to how a construction worker knows which suppliers to get specific materials from.
