"If you try to type or check the box in the current version of the example, you’ll see that React ignores your input. This is intentional, as we’ve set the value prop of the input to always be equal to the state passed in from FilterableProductTable."

The above paragraph is located in the step 5 in article of "Thinking in React". However I think it is more likely describing the step 4.

从“Thinking in React”文章开始，找到第 5 步中引用的段落。将其说明与第 4 步进行比较，然后在适当的情况下移动它；文章应将该段落放在它所描述的步骤旁边。
