检查是否有调用自身的函数。例如

export default class DateUtils {
  static now = (): Date => {
    return DateUtils.now()
  }
}

在我的例子中，我有两个同名的变量!

我也面临着同样的问题 我已经通过删除在ajax上使用了两次的字段名来解决它 如

    jQuery.ajax({
    url : '/search-result',
    data : {
      searchField : searchField,
      searchFieldValue : searchField,
      nid    :  nid,
      indexName : indexName,
      indexType : indexType
    },
.....

遇到同样的问题，不知道怎么回事，开始责怪巴别塔;)

在浏览器中不返回任何异常的代码:

if (typeof document.body.onpointerdown !== ('undefined' || null)) {

问题是严重创建||(或)部分Babel创建自己的类型检查:

function _typeof(obj){if(typeof Symbol==="function"&&_typeof(Symbol.iterator)==="symbol")

所以删除

|| null

让巴别塔翻译起作用了。

这也会导致最大调用堆栈大小超过错误:

var items = [];
[].push.apply(items, new Array(1000000)); //Bad

我也一样:

items.push(...new Array(1000000)); //Bad

来自Mozilla文档:

But beware: in using apply this way, you run the risk of exceeding the JavaScript engine's argument length limit. The consequences of applying a function with too many arguments (think more than tens of thousands of arguments) vary across engines (JavaScriptCore has hard-coded argument limit of 65536), because the limit (indeed even the nature of any excessively-large-stack behavior) is unspecified. Some engines will throw an exception. More perniciously, others will arbitrarily limit the number of arguments actually passed to the applied function. To illustrate this latter case: if such an engine had a limit of four arguments (actual limits are of course significantly higher), it would be as if the arguments 5, 6, 2, 3 had been passed to apply in the examples above, rather than the full array.

所以尝试:

var items = [];
var newItems = new Array(1000000);
for(var i = 0; i < newItems.length; i++){
  items.push(newItems[i]);
}

我有这个错误，因为我有两个同名的JS函数
