Action performed

Format javascript file with HookyQR.beautifyFile command:

((a, b) => { return a &&= b })(true, false)

Expected results

&& and = should not include any space (valid syntax):

((a, b) => {
  return a &&= b
})(true, false)

Actual results

Space between && and = (invalid syntax) :

((a, b) => {
  return a && = b
})(true, false)
