数组去重

var all = [
{ timeStart: '9:00', timeEnd: '10:00', },
{ timeStart: '10:00', timeEnd: '11:00', },
{ timeStart: '11:00', timeEnd: '12:00', },
{ timeStart: '12:00', timeEnd: '13:00', }
]

　　//去除timeStart相等的

console.log(uniqueArray(all, timeStart));

//数组去重复
            function uniqueArray(array, key) {
