这是数组赋值的红宝石是如何工作的。

That's just how array assignment works in Ruby.

youdao

例如，性质用一维数组赋值，2元谓词用2维数组赋值，等等。

For instance, properties are assigned by one-dimensional arrays, predicates of arity 2 by two-dimensional arrays, and so on.

第二，既然这个任务类是Runnable，为了防止DCE，必须把数组访问的结果赋值给state字段(以及覆盖的toString方法中需要使用的state)。

Second, given that this task class is a Runnable, the result of the array access needs to be assigned to the state field (and state needs to be used in an overriding toString method) to prevent DCE.

All right, so let's make it the list 123.

好，还是给这个数组赋值为123好不好？

So I can concatenate techs plus ivys and assign that result to univs, and then when I print it you'll notice I just get a list of five strings.

和ivys数组用加号串联运算,并把结果赋值给univs数组，接下来我显示下univs的结果,你注意到我得到了一个。

You can also assign to a list, or to an element of a list. So ivy sub 1, f -15 or example, could be assigned minus 15, and that will actually mutate the list.

此外你还可以给一个数组，或者数组内部的元素赋值,比如ivy。sub，可以被赋值为，这确实改变了数组。
