What is the purpose of using "/" to display the index page?

I'm trying to understand the purpose of the "/" in this code snippet:

app.get("/", (req, res) =>// The / is commonly used as a shortcut for index.html but could vary depending on the configuration
{
    res.render(index);
}); 

Answer №1

Classic and convenient.

If your domain is sample.net, it's ideal to have the homepage accessible at https://sample.net/ (meaning the path should be just / right after the domain) for easy access without having to type

https://sample.net/something-else
.

Answer №2

Let's say you have a website with the default page as example.com. This default page would display the index page.

If you wanted to create a different page, like example.com/about, you would use /about and render the about page accordingly.

For instance, in your code:

app.get("[Whatever directory]" ...)
{
    res.render([whatever page])
    ...
