❓ Frequently Asked Questions
What does escaping a string mean?
Escaping converts special characters like quotes, backslashes, and newlines into safe representations so they can be used in code without breaking syntax.
How do I escape a JavaScript string?
Special characters like quotes (`"`, `\'`) and line breaks (`\n`) are prefixed with backslashes so they are treated as literal values in JavaScript.
What is JSON string escaping?
JSON escaping ensures strings are valid inside JSON by escaping quotes, control characters, and backslashes according to the JSON specification.
How does HTML escaping work?
HTML escaping converts characters like `<`, `>`, and `&` into entities (`<`, `>`, `&`) to prevent rendering or injection issues.
Why is SQL string escaping important?
Escaping single quotes prevents syntax errors and reduces the risk of SQL injection by ensuring user input is treated as data, not executable code.
Can I reverse escaped strings?
Yes. Switch to unescape mode to convert escaped sequences back into their original readable form.
