What characters does JSON escaping handle?

JSON escaping replaces double quotes, backslashes, and control characters (newline, tab, carriage return, and others) with their escape sequences so the string is valid inside a JSON value.

How is SQL escaping different from JSON?

SQL string escaping (ANSI standard) doubles any single quotes inside the string — turning ' into ''. This prevents SQL injection when a value is embedded in a single-quoted SQL literal.

What does regex escaping do?

Regex escaping adds a backslash before every character that has special meaning in a regular expression: . ^ $ * + ? { } [ ] | ( ) \. This makes the string safe to use as a literal match pattern.

When would I need to escape a JavaScript string?

When building a string literal programmatically — for example injecting content into a script tag or a template. JavaScript escaping handles quotes, backslashes, newlines, and other control characters.
