雖然通過了，但是是不是還不夠嚴謹??？
function?arraysSimilar(arr1,?arr2)?{
??if?(!(arr1?instanceof?Array?&&?arr2?instanceof?Array))?{
????return?false;
??}
??if?(arr1.length?!==?arr2.length)?{
????return?false;
??}
??return?iterateArr(arr1)?===?iterateArr(arr2);
}
function?iterateArr(arr)?{
??return?arr.map(getType).sort().join("");
}
function?getType(data)?{
??if?(typeof?data?===?"object")?{
????return?Object.prototype.toString.call(data);
??}
??return?typeof?data;
}

我是這么寫的,注意日期類型和null就行了
????arr1?=?arr1.map(ele?=>?{???????? ????????return?ele?===?null???'null'?:???????????? ????????ele?instanceof?Date?????????????????? ????????????'date'?:???????????????? ????????typeof?ele????}).sort()???? ????arr2?=?arr2.map(ele?=>?{???????? ????????return?ele?===?null???'null'?:???????????? ????????ele?instanceof?Date?????????????????? ????????'date'?:???????????????? ????????typeof?ele????}).sort()???? ????const?result?=?arr1.every((element,index)?=>?element===arr2[index]) ????return?result
