不使用任何字母javascript就返回hello world
[英]return hello world without using any letters javascript
问题描述
This question is really bothering me! 
这个问题真的困扰我！
My original solution looked like this: 我原来的解决方案如下所示：
function f(){
return String.fromCharCode(72,101,108,108,111,44,32,119,111,114,108,100,33);
}
The error I am getting is Your solution uses o letter 我收到的错误是Your solution uses o letter
My thought was that it was that there is an o in fromCharCode but then I also tried generating "Hello, world!" 我以为那是fromCharCode中有一个o ，但后来我也尝试生成"Hello, world!" here to guarantee no o is in the function, however, I saw the same error. 这里保证函数中没有o ，但是，我看到了相同的错误。
Can anyone spot anything silly I may be missing? 谁能发现我可能会错过的任何愚蠢的东西？

This works: 这有效：
f = () => '\x48\x65\x6C\x6C\x6F\x2C\x20\x77\x6F\x72\x6C\x64\x21';
