Javascript 我使用IE的Angle factory/service中有两个错误，但Chrome或Edge中没有错误

我在IE中遇到了两个错误，而在Chrome或Edge中没有遇到。

var groupedArray = Object.keys(groupedObj).sort()
    .map(key=>groupedObj[key]);

可能是与特定代码和IE的兼容性问题，也可能是我的代码本身导致了错误

第一个错误：

var groupedArray = Object.keys(groupedObj).sort()
    .map(key=>groupedObj[key]);

语法错误（无详细说明）：在这行代码上：

var groupedArray = Object.keys(groupedObj).sort().map(key=>groupedObj[key]); 

第二个错误：

var groupedArray = Object.keys(groupedObj).sort()
    .map(key=>groupedObj[key]);

我的问题是在我的服务/工厂中使用ES2015 JavaScript代码。这是无法与IE相比的，IE已经两年没有新版本了

所以，改变

var groupedArray = Object.keys(groupedObj).sort()
    .map(key=>groupedObj[key]);

至：

            createArray: createArray,
            setItemCount: setItemCount,
            setSeries: setSeries
        };

        return service;

        function createArray(dateArray, valueArray) {
            var arr = dateArray.map(function (s) {
                var week = getWeekNumber(parseISOLocal(s));
                return week[0] + ('0' + week[1]).slice(-2) + ':' + s;
            }).sort();
            var results = createGroupedArray(createGroupObject(arr));
            if (valueArray && valueArray.length === dateArray.length) {
                for (var i = 0; i < results.length; i++) {
                    results[i] = results[i].map(function (date, index) {

解决了我的两个错误

我不明白。你写下你希望你的代码与IE兼容，但你故意使用在IE之后很久才引入的技术。你如何解释这一矛盾？嗨，zeroflagL，你指的是角度的使用，还是一行特定的代码？我的整个项目都是在IE中进行的，今天我在一个新的方法和服务中发现了这两个错误。这就是为什么我在寻求如何解决这个问题的方向。我希望这能澄清这一点。您使用ES2015（

key=>groupedObj[key]

），它是在IE的最后一个版本推出两年后推出的，更不用说旧版本了。感谢您的澄清。我确实认为这就是问题所在。您是否有建议在可接受的JavaScript版本中重写该行？那将是赢家D
