What potential issues can arise from adding script tags to files without proper placement in HTML documents?

Adding script tags to files without proper placement in HTML documents can lead to errors such as scripts not executing correctly or causing the page to load slowly. To solve this issue, always ensure that script tags are placed within the <head> or <body> section of the HTML document.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;Example Page&lt;/title&gt;
    &lt;script src=&quot;script.js&quot;&gt;&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Hello, World!&lt;/h1&gt;
&lt;/body&gt;
&lt;/html&gt;
