I'm amazed if the second syntax works at all your middle operation should evaluate to true for each loop you want to complete and false as soon as you want to be done looping. As for any issues with your first for loop, a JavaScript is function scoped so that inner var statement will...
This will output a single number, breaking out of the outer loop. The unfortunate thing is that break sort of works as people expect with ForEach-Object, but in my opinion, it's sort of an accident that falls out from the implementation. Under the covers, the break turns into an except...
If you're working with a collection or array, you often use a foreach loop. A collection is a group of similar objects, and the foreach loop lets you carry out a task on each item in the collection. This type of loop is convenient for collections, because unlike a for loop, y...

使用IDE是完全避免任何语法错误的方法。我甚至会说，没有使用IDE的工作方式有点不专业。为什么呢？因为现代IDE在你输入每个字符后都会检查你的语法。当你编写代码并且整行都变成红色，并显示一个大的警告通知，告诉你确切的类型和语法错误的精确位置时，就绝对没有必要再去寻找另一种解决方案。
