What are HTML Entities?

HTML entities are special character codes used to represent reserved characters, symbols, and Unicode characters in HTML and XML documents. Common HTML entities include &amp; for ampersand (&), &lt; for less-than (<), &gt; for greater-than (>), &quot; for quotation marks ("), and &#39; for apostrophes ('). HTML entities prevent parsing errors, protect against XSS attacks, and enable proper display of special characters in web browsers.
