const object1 = {};
object1[Symbol.toStringTag] = 'Array';
console.log(type(object1)); // Array
是否可以去掉47行的if判断,直接使用对象的constructor
if(x.constructor == Object){
return clsLow;
}
c = toString.call(x).slice(8, -1).toLowerCase();
I don't think that's a good idea to toLowerCase
.
It's easy to confuse the Primitive values
and Objects
.
For example:
let p= false;
let o = new Boolean(false);
console.log(type(p), !!p)// boolean false
console.log(type(o), !!o)// boolean true
There are no difference between type(p)
and type(o)
.
