Another form of the for loop is for...in. This can be used with an array, list, or tuple. The for...in loop iterates through a list or collection and returns an index on each iteration. Example: for..in Loop Copy let arr = [10, 20, 30, 40]; for (var index in arr) { ...

但是,我们知道使用相同的参数调用“Symbol.for()”方法实际上返回的是相同的Symbol值。因此,可能出现多个“unique symbol”类型的值实际上是同一个Symbol值的情况。由于设计上的局限性,TypeScript目前无法识别出这种情况,因此不会产生编译错误,开发者必须要留意这种特殊情况。
