The problem was that you opened the Node js repl while everyone automatically assumed you were in the command prompt  For what it s worth you can run a javascript file from the repl with the  load command  For example    load c  users username documents script js   The same command can also be used in the command prompt if you first start node inside the command prompt by entering node with no arguments  assuming node is in PATH    I find it fascinating that 1 everyone assumed you were in the command prompt rather than repl  2 no one seems to know about  load  and 3 this has 273 upvotes  proving that a lot of other node js beginners are similarly confused

Here are the exact steps I just took to run the  Hello World  example found at http   nodejs org   This is a quick and dirty example  For a permanent installation you d want to store the executable in a more reasonable place than the root directory and update your PATH to include its location    Download the Windows executable here  http   nodejs org  download Copy the file to C   Create C  hello js Paste in the following content        var http   require  http        http createServer function  req  res          res writeHead 200    Content-Type    text plain           res end  Hello World n           listen 1337   127 0 0 1        console log  Server running at http   127 0 0 1 1337        Save the file Start -  Run    -  cmd c  C  node hello js  Server running at http   127 0 0 1 1337     That s it  This was done on Windows XP
