HTML entities are special coding sequences used to represent characters that either have special meaning in HTML (like < and >) or cannot be typed directly (like © or €). They start with & and end with ; — for example, < represents the less-than sign (<).
Encoding is essential when you want to display HTML code as plain text on a webpage. Without encoding, the browser would interpret <div> as an actual HTML element instead of showing the literal text '<div>'. It's also important for preventing XSS attacks when handling user input.
Named entities use descriptive names like & or <, while numeric entities use decimal (&) or hexadecimal (&) codes. Both work identically in browsers. Named entities are more readable, while numeric entities can represent any Unicode character.
