将数组中的项移动到另一个数组-Moveiteminarraytoanotherarray

yep, it would look like this:

是的，它看起来像这样：

y.push x.delete_at(1)

delete_at will delete an element with given index from an array it's called on and return that object

delete_at将从调用它的数组中删除具有给定索引的元素并返回该对象

A special code for this example. It might not work on your other arrays. Instead of actually moving element, let's take the old array apart and construct two new arrays.

此示例的特殊代码。它可能不适用于您的其他阵列。我们不是实际移动元素，而是将旧数组拆开并构造两个新数组。

x = ['a', 'b', 'c']

x, y = x.partition {|i| i != 'b'}

x # => ["a", "c"]
y # => ["b"]

The delete_at approach is likely better for your situation, but, you know, it's good to know alternatives :)

delete_at方法可能对你的情况更好，但是，你知道，知道替代方案很好:)

Yes. For a specific element:

是。对于特定元素：

y = []
y <

y = []
y <
