Nodejs is a scripting language (like Python or Ruby, and unlike PHP or C++). To run your code, you need to enter a command in the terminal / shell / command prompt. Look for an application shortcut in your operating system by one of those names.
The command to run in the terminal will be
node server.js
But you will first need to browse in the terminal to the same folder as the file server.js. The syntax for using the terminal varies by operating system, look for its documentation.
