## Description
|
||
|
|
<section id='description'>
|
||
|
|
ES6 agrega un buen soporte para definir fácilmente literales de objetos.
|
||
|
|
Considera el siguiente código:
|
||
|
|
<blockquote>const getMousePosition = (x, y) => ({<br> x: x,<br> y: y<br>});</blockquote>
|
||
|
|
<code>getMousePosition</code> es una función simple que devuelve un objeto que contiene dos campos.
|
||
|
|
ES6 proporciona el azúcar sintáctico para eliminar la redundancia de tener que escribir <code>x: x</code> . Simplemente puede escribir <code>x</code> una vez, y se convertirá a <code>x: x</code> (o algo equivalente) debajo del capó.
|
||
|
|
Aquí se reescribe la misma función de la anterior para usar esta nueva sintaxis:
|
||
|
|
<blockquote>const getMousePosition = (x, y) => ({ x, y });</blockquote>
