HTML Output Interpreted as Plain Text Instead of Received as HTML

The question here concerns a scenario where HTML output is rendered as plain text instead of being parsed as proper HTML. A basic Go implementation is provided, but the rendered output shows verbatim HTML code within pre tags.

To rectify this issue, the Content-Type header must be set to specify that the response is HTML. This ensures that the browser interprets and renders the output correctly. The following code addition sets the Content-Type header:

w.Header().Set("Content-Type", "text/html")

By incorporating this adjustment, the HTML output will be properly recognized as an HTML document by the browser, allowing for accurate rendering of the desired content.
