分配给数组的语法 [英] syntax for assigning to an array

问题描述

在PHP中，如果函数返回一个数组，那么捕获

的返回值是相当常见的：


<？php

列表（$ foo，$ bar，$ baz）= some_function_that_return_an_array（）;

？>


在Javascript中，相同的（可接受的）代码是否会这样？


[foo，bar，baz] = some_function_that_return_an_array（）;


我通常运行我的代码通过JSLint作为一个快速的健全性检查，但这个

表达式使它死亡。显然它是JSLint中的一个解析错误，但是我想要确保我没有完全关闭

。谢谢。

In PHP, if a function returns an array it''s fairly common to capture
its return values like this:

<?php
list($foo, $bar, $baz) = some_function_that_return_an_array();
?>

In Javascript, would the equivalent (acceptable) code be this?

[foo, bar, baz] = some_function_that_return_an_array();

I usually run my code through JSLint as a quick sanity check, but this
expression makes it die. Clearly it''s a parsing bug in JSLint, but I
also wanted to make sure that I wasn''t doing something completely off
the wall. Thanks.

推荐答案

foo，

bar，

baz ）= some_function_that_return_an_array（）;
