What is Node.js Exactly? – a beginners introduction to Nodejs

What exactly is node.js? Is it a command-line tool, a language, the same thing as Ruby on Rails, a cure for cancer?

If you’re new to web development, it can be a bit confusing as to what exactly node.js is and to what you should do with it, and there’s a lot of information out there…most of which seems to be tailored towards genius-level developers.

So, here’s a node.js introduction for those who have no idea what it is.

To wrap it up, we’re going to spin up a quick web server in node.js just to show you how easy it is.

    Node.Js is the future of backend development. Its ability to not only be easy to easy for front end developers to pick up makes it very powerful. Reading articles on websites like http://www.thefuturedeveloper.com makes it easy for developer to attain these new skills.

    Any beginner who doesn't know basic code syntax should probably not hang around node js yet lmao just stick to learning how to code first rather than click around and get mindblown. Node js is sth to learn as one of the endgoals: to begin doing webapps and projects.
    On that note, thanks for the video! I think you missed out mentioning what 'exports' is by default (a JSON). That realisation for me made things a lot clearer. Nonetheless, good video!

    This might be a introduction to Node.js for people who are already at least intermediate level web developers and/or programmers, but it presumes quite a bit of knowledge in a number of areas of expertise to be called a "beginner's introduction."
