[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);
 };
}
