话不多说直接上代码，菜鸟一只，有误请指教，感谢！

function getHoursList () {
        let date = new Date()
        let startCount = date.getHours() + 1 // date.getHours() // 获取当前小时
        let dateType = '今天'
        let hoursCount = 24
        let hoursList = []
        for (let i = 0; i <= hoursCount - 1; i++) {
            console.log(i)
             if (startCount === 0) {
                startCount = 24
                dateType = '昨天'
            }
            startCount = startCount - 1
            hoursList.push({ date: dateType, hours: startCount >= 10 ? startCount + '时' : '0' + startCount + '时' })
        }
        return hoursList
    }
let hoursListArr = getHoursList ()
console.log(hoursListArr)
