Why URL & HTML Encoding is Critical for Developers
1
Percent Encoding in URLs
Characters like spaces (`%20`), `?`, `&`, and `#` have special syntactic meanings in HTTP requests. Encoding prevents broken query strings.
2
Cross-Site Scripting (XSS) Prevention
Escaping user inputs to HTML entities (`<` for `<`, `>` for `>`) stops malicious script injection in web templates.
3
Instant Client-Side Encoding
Runs directly using JavaScript `encodeURIComponent` and DOM entity mappers without leaking search queries to third parties.
