This is just a nod to the handy little Visual Studio Code Extension: Preview on Web Server.
Now you can configure a task, or run a command, or set up a local web server yourself… but why not just install this extension and then just hit CTRL + SHIFT + L to load the web page into a browser, using a local web server.
When you just want to quickly view a web page, with the scripts being loaded correctly relative to the root path; this Visual Studio Code extension is a great time saver.
