This is the first in a series of lessons that will teach you how to use JavaScript with Node. In this first lesson, you will learn what Node is from a conceptual standpoint and then you will install Node. Then, you will verify that Node is installed. Lastly, you will create two Node applications. In future lessons, you will learn to use NPM (node package manager), Express (a web development framework that works with Node), and tie in a database such as postgres or sqllite.
