this is the shelf above the collar button that uses javascript to implement circular queues. I want to ask
var obj = Object.create (MyCircularQueue). Create New (k)
what is the meaning of createNew (k).

< del > is to implement a createNew method on the prototype of MyCircularQueue , and return an instance of MyCircularQueue . < / del >
should directly implement createNew on MyCircularQueue , that is, a static method of MyCircularQueue class, returning an instance of MyCircularQueue .

var obj = Object.create(MyCircularQueue).createNew(k)
//  __proto__ MyCircularQueueFunction
var tempObj = Object.create(MyCircularQueue);

// 
// tempOjb createNew__proto__MyCircularQueue
//  MyCircularQueue.createNew = function(){}; 
MyCircularQueue.createNew = function(obj){
    return new MyCircularQueue(obj);
}
tempObj.createNew(k);
