js生成一年12个月和每月的天数

               let date = new Date()
                for (let m = 1; m < 13; m++) {
                    let num = new Date(date.getFullYear(), m, 0).getDate();
                    for (let i = 1; i < num + 1; i++) {  //再把天数循环出来
                        let array = [];

                        array[0] = i + ‘日‘;
                        array[1] = m + ‘月‘;
                        array[2] = 0;
                        this.baseData.push(array)
                    }
                }
                console.log(this.baseData) //输出每个月的天数
