JavaScript自定义数据类型判断函数

function judgeType(ele){
    let res = typeof ele;
    if(res === "object"){
        // 短路表达式，第一个成立则返回第二个的值，第一个不成立，则返回第一个的值
        Object.prototype.toString.call(ele) === "[object Object]" && (res = "object");
        Object.prototype.toString.call(ele) === "[object Array]" && (res = "array");
        Object.prototype.toString.call(ele) === "[object Date]" && (res = "date");
        Object.prototype.toString.call(ele) === "[object Null]" && (res = "null");
        Object.prototype.toString.call(ele) === "[object RegExp]" && (res = "RegExp");
    }
    return res;
}
// ----------一般数据类型---------
console.log(judgeType(23));     //  number
console.log(judgeType(false));   //  boolean
console.log(judgeType("23"));    // string
console.log(judgeType(undefined)); //    undefined
console.log(judgeType(NaN));     //  number
console.log(judgeType(function (){}));  // function
console.log("===============================");
// ---------- 对象类型数据---------
console.log(judgeType(null));    // object   null
console.log(judgeType({}));     // object   object
console.log(judgeType([]));     // object   array
console.log(judgeType(new Date()));       // object   date
console.log(judgeType(new RegExp()));     // object RegExp
