JavaScript is a lightweight and imprecise programming language with basic syntax, but although lightweight and simple, but sometimes it can get you, this is an interesting article, perhaps you have written a JavaScript function or the use of JavaScript "class" For example: var mydate = new Date (), you are familiar with the new keyword and the ability to pass function parameters via the New keyword.
Take a look at the following code:

The code is as follows Copy Code

function MyClass () {
Console.log (' initialized! ');
Set A, as an example
This.dirty = true;
}
var instance = new MyClass;
>> "initialized!"

So this is what I want to tell you, I don't know what it is, just think it's interesting.
