説明

React 16 does not ignore Boolean values for unknown props anymore.

So while this code "worked" in react 15:

<div onClick={!disabled && onClick}/>

It would try to assing false to the DOM elements onClick handler when disabled === true (which would be ignored by the browser).

React 16 will print an error message in the console though.

How about a rule that does not allow boolean results for unknown props?
