如何获得完整日期中2个日期之间的差异(我不想要一天中的任何一小部分)

var date1 = new Date('7/11/2010');
var date2 = new Date('12/12/2010');
var diffDays = date2.getDate() - date1.getDate(); 
alert(diffDays)

我试过上面的但是这没用.

我一直试图计算中位数,但我仍然有一些数学问题,因为我无法得到正确的中值,无法找出原因.这是代码;

class StatsCollector {

    constructor() {
        this.inputNumber = 0;
        this.average = 0;

        this.timeout = 19000;

        this.frequencies = new Map();
        for (let i of Array(this.timeout).keys()) {
            this.frequencies.set(i, 0);
        }
    }

    pushValue(responseTimeMs) {
        let req = responseTimeMs;
        if (req > this.timeout) {
            req = this.timeout;
        }

        this.average = (this.average * this.inputNumber + req) / (this.inputNumber + 1);

        console.log(responseTimeMs / 1000)
        let groupIndex = Math.floor(responseTimeMs / 1000);
        this.frequencies.set(groupIndex, this.frequencies.get(groupIndex) + 1);

        this.inputNumber += 1;
    }

    getMedian() {
        let medianElement = 0; …
