They are\nthere to show the start of each command.\nLines that don’t start with <code>$</code> or <code>></code> character show the output of the previous\ncommand.\nFirst, make sure to have downloaded and installed Node.js. See <a href=\"https://nodejs.org/en/download/package-manager/\">this guide</a>\nfor further install information.\nNow, create an empty project folder called <code>projects</code>, then navigate into it.\nLinux and Mac:\n<pre><code class=\"language-console\">$ mkdir ~/projects\n$ cd ~/projects\n</code></pre>\nWindows CMD:\n<pre><code class=\"language-console\">> mkdir %USERPROFILE%\\projects\n> cd %USERPROFILE%\\projects\n</code></pre>\nWindows PowerShell:\n<pre><code class=\"language-console\">> mkdir $env:USERPROFILE\\projects\n> cd $env:USERPROFILE\\projects\n</code></pre>\nNext, create a new source file in the <code>projects</code>\nfolder and call it <code>hello-world.js</code>.\nOpen <code>hello-world.js</code> in any preferred text editor and\npaste in the following content:\n<pre><code class=\"language-js\">const http = require('http');\n\nconst hostname = '127.0.0.1';\nconst port = 3000;\n\nconst server = http.createServer((req, res) => {\n res.statusCode = 200;\n res.setHeader('Content-Type', 'text/plain');\n res.end('Hello, World!\\n');\n});\n\nserver.listen(port, hostname, () => {\n console.log(`Server running at http://${hostname}:${port}/`);\n});\n</code></pre>\nSave the file, go back to the terminal window, and enter the following command:\n<pre><code class=\"language-console\">$ node hello-world.js\n</code></pre>\nOutput like this should appear in the terminal:\n<pre><code class=\"language-console\">Server running at http://127.0.0.1:3000/\n</code></pre>\nNow, open any preferred web browser and visit <code>http://127.0.0.1:3000</code>.\nIf the browser displays the string <code>Hello, World!</code>, that indicates\nthe server is working."
