Frequently Asked Questions
Why do I need to encode HTML entities?
HTML encoding prevents browsers from interpreting special characters as HTML tags or code. This is critical for security (preventing XSS attacks) and for correctly displaying characters like <, >, and & on web pages.
What is XSS and how does encoding prevent it?
XSS (Cross-Site Scripting) is an attack where malicious scripts are injected into web pages. HTML encoding converts < and > to their entity forms, preventing injected code from being executed by the browser.
Should I encode all text before displaying it?
Yes, any user-generated or dynamic content should be HTML encoded before rendering in a web page. Most modern frameworks (React, Angular, Vue) do this automatically, but server-rendered content needs explicit encoding.
