js判断object的具体类型（或者说判断object的类class）

Object.prototype.toString.call(t);

The most accurate way to check JS object's type?

Ask Question

The typeof operator doesn't really help us to find the real type of an object.

I've already seen the following code :

Object.prototype.toString.apply(t)

Question:

Is it the most accurate way of checking the object's type?
