Part of the improve error messages initiative. Based on a resource of JSON.parse() errors found at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/JSON_bad_parse added support for: - 'Bad control character in string literal' - 'Bad Unicode escape' Previously JSON.parse('"a\bz"') would output: SyntaxError: Unexpected token in JSON at position 2 Now the output is: SyntaxError: Bad control character in string literal in JSON at position 2 Previously JSON.parse("[\"\\t\\u") would output: SyntaxError: Unexpected end of JSON input Now the output is: SyntaxError: Bad Unicode escape in JSON at position 6 Bug: v8:6551 Change-Id: I3ba5450c41b8a388643a15bc58e4e3fc75855d13 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3652254 Reviewed-by: Toon Verwaest <verwaest@chromium.org> Commit-Queue: Issack John <issackjohn@microsoft.com> Cr-Commit-Position: refs/heads/main@{#80642}
