JSON escaping is stricter - it uses double quotes and requires escaping certain characters like forward slashes. JavaScript escaping supports both quote styles and has additional escape sequences like \x hex codes.
When you want to match literal special characters (like . or *) in a regular expression, you need to escape them with a backslash so the regex engine treats them as literal characters, not operators.
Yes. Newlines are converted to \n in JSON/JavaScript escaping, and the tool correctly unescapes \n back to actual line breaks.
