Frequently Asked Questions
Why do strings need to be escaped?
Special characters like quotes, backslashes, and newlines have syntactic meaning in most programming languages and data formats. Escaping replaces them with safe sequences (e.g., \" for a quote in JSON) so the string is interpreted correctly.
What is the difference between escape and encode?
Escaping adds a prefix (like \) to characters within the same character set. Encoding transforms characters into a different representation (like %20 for URL encoding or & for HTML entities).
When do I need to escape strings?
Escape strings when embedding them in JSON, building SQL queries (use parameterized queries instead when possible), writing regex patterns, inserting text into HTML attributes, or including special characters in JavaScript string literals.
