Method of JS Encapsulation

1, JS package is to try to use the way to simplify, internal logic and use decoupling. In layman's terms, you only need to know the parameters and return values when you use them, and other conditions try not to use people to set them up.

2, the method of JS package has the function way, the way of the object, the way of closing the packet.

Example

1) function mode
function KK (A, b) {
There is no need to worry about how to deal with A/b internally.
}

2) Object mode
function KK (A, b) {
This.x = A;
This.y = b;
}
var k = new KK;//through object-oriented approach
alert (k.x);
3) Closure method
function KK (A, b) {
var k = 1;
return function tt () {
k++;
}
}
var u = KK (on);
U ();//Closure Implementation cumulative
U ();//Closure Implementation cumulative
