[Partial application without Bind] Why a few of test cases are passed, some are failed

[hungdao-testing]

Hi all,

Would you guys have a look at my code to help me figure out what wrong in my code that causes some cases are passed , some are failed

var slice = Array.prototype.slice;
function logger(namespace) {
  // SOLUTION GOES HERE

  let arr = slice.call(arguments);
  return function (...params) {
    arr.push.apply(arr, params);
    console.log.apply(null, arr);
  };
}
