Docs: not being accurate in one of faq examples

In a Passing Function to Components page in FAQ section. There is an example that claims that two functions are equivalent which is not so accurate.

<button onClick={() => this.handleClick(id)} />

<button onClick={this.handleClick.bind(this, id)} />

• The first one only receives the id
• the second will receive Synthetic click event as the second argument beside id

打开 FAQ 的“Passing Function to Components”页面，并检查“How do I pass a parameter to an event handler or callback?”下方的示例。更新说明，使其准确描述每种 handler 形式接收的参数，然后确认示例及其周围的文本不再声称这两个函数完全等价。
