Why Escape JSON Strings?
JSON requires certain characters such as quotes, backslashes, and line breaks to be escaped when they appear inside string values. Proper escaping prevents invalid payloads and parser errors, especially when inserting user text into JSON requests, app settings, or serialized application data.
