E0060: invalid hex escape sequence

String literals and template literals can contain escape sequences, including \x followed by two hexadecimal digits. It is an error for \x to be followed by anything except two hexadecimal digits:

let gameTitle = isBlue
  ? 'Pok\xmon Blue'
  : 'Pok\xe9mon Red';

let path = 'c:\xampp\bin\apache.exe';

To fix this error, complete the sequence by writing two hexadecimal digits:

let gameTitle = isBlue
  ? 'Pok\xe9mon Blue'
  : 'Pok\xe9mon Red';

Alternatively, escape \ with an extra \:

let path = 'c:\\xampp\\bin\\apache.exe';

Introduced in quick-lint-js version 0.2.0.
