What are HTML Entities?

HTML entities are special character sequences used to display reserved characters, invisible characters, and special typography in HTML documents. For example, the less-than symbol (<) is reserved for HTML tags; to display it safely as text, developers use the entity &lt;.

Encoding HTML entities is a fundamental security practice to prevent Cross-Site Scripting (XSS) attacks. By sanitizing user input and converting reserved characters into their corresponding entities, you prevent malicious scripts from being accidentally executed by the browser.
