🧠 HOW HTML ENTITIES WORK EXPLAINER
1

HTML parsers interpret characters like <, >, and & as markup syntax. To display them literally, they must be escaped.

2

Encoding uses a hidden <div> element — setting textContent automatically escapes all special chars via the browser's built-in HTML serializer.

3

Decoding does the reverse — setting innerHTML then reading textContent has the browser parse entities back to their actual characters.

4

This technique is critical for preventing XSS attacks — always encode user-supplied data before inserting it into HTML!
