Node.js makes it possible for you to run JavaScript programs outside of a web browser or on a server. To run a Node.js application on Windows, follow these three steps.
- Locate Command Prompt by entering cmd into the search bar. Click cmd in the search results to open the Command Prompt.
- Enter the following command, then press Enter to create a file named test-node.js containing a simple application that will print out the result 1 + 1.
echo console.log(1+1); >> test-node.js - Type
nodefollowed by the name of the application, which is test-node.js in this case, and then press Enter.
The result of running the application will be printed out to the command prompt.node test-node.js
