| ## Description
 | ||
| <section id="description"> ES6为轻松定义对象文字添加了一些很好的支持。请考虑以下代码: <blockquote> const getMousePosition =(x,y)=>({ <br> x:x, <br> y:y <br> }); </blockquote> <code>getMousePosition</code>是一个简单的函数,它返回一个包含两个字段的对象。 ES6提供了语法糖,以消除必须写入<code>x: x</code>的冗余。您可以简单地编写一次<code>x</code> ,它将被转换为<code>x: x</code> (或类似的东西)。这是从上面重写的相同函数使用这个新语法: <blockquote> const getMousePosition =(x,y)=>({x,y}); </blockquote></section>
