There are many open source packages available on npm, so before starting a project, take some time to explore so you don't end up recreating the wheel for things like working with dates or fetching data from an API.",

Node.js comes with a handful of built-in modules — small, independent programs — that help with this. Some of the core modules include HTTP, which acts like a server, and File System, a module to read and modify files.",
-          "In the last set of courses you learned to install and manage packages from npm, which are collections of smaller modules. These packages can help you build larger, more complex applications.",
-          "Express is a lightweight web application framework, and is one of the most popular packages on npm. Express makes it much easier to create a server and handle routing for your application, which handles things like directing people to the correct page when they visit a certain endpoint like <pre>/blog</pre>.",
-          "In this course, you'll learn the basics of Node and Express including how to create a server, serve different files, and handle different requests from the browser."
