我经常看到JavaScript片段“压缩/嵌套”，这使得编辑非常困难。
是否可以转换此代码以便于再次阅读？
以下是代码：
eval(function(p, a, c, k, e, d) {
e = function(c) {
return (c < a ? '' : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if (!''.replace(/^/, String)) {
while (c--) {
d[e(c)] = k[c] || e(c)
}
k = [function(e) {
return d[e]
}];
e = function() {
return '\\w+'
};
c = 1
};
while (c--) {
if (k[c]) {
p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c])
}
}
return p
}

仅供参考，我是一名JavaScript初学者，所以请对我好：D
我用谷歌搜索过，遗憾的是我找不到任何解决方案。
提前感谢您最好的问候

Javascript可以使用自定义算法缩小，因此没有通用的方法来减少它。
我已经编写了a 4kb demo，其中js由单个字符串自定义算法base85编码组成，其中包含手动预处理的自定义算法压缩版本，然后是clojure编译器压缩的javascript源。
我非常怀疑一般工具可以自动将其解码为更易读的形式。
您必须按照javascript正在执行的步骤逐个处理，这包括执行string.IsNullOrWhiteSpace代码。
请注意，在other cases中，javascript代码可以是来自另一种语言的真实编译器的输出，其中所有高级符号信息都已被删除（实际上它在Javascript中从未出现过，它只出现在原始语言形式）。在那种情况下，你得到的是真正的＆＃34;原创＆＃34; javascript，你只能尝试缩进它，但这不会有太多的可读性。
你可以找到的是通用的＆＃34; beautyfier＆＃34;它只会重新加入Javascript代码并添加一些空格，或者甚至可能是能够减少特定缩放器生成的代码的工具（特别是通用的缩小器） ：他们可以使用的Javascript越少，他们能够做的就越少...请记住，在Javascript中可以获得函数的源代码，因此代码依赖于原始源代码函数是有效的Javascript，无法在不改变其行为的情况下进行微调。）

如果你删除了开头的eval并将最外层函数的返回值打印到控制台（console.log），你可以看到一个缩小的，但仍然更易读的代码版本被执行。
这是故意处理一些工具，旨在将原始的JavaScript 不可读保留在脚本小子眼中。
