出于某种原因...为什么不能正常工作
当过我尝试从replace.letters
的Object.keys
和使用Object.keys
新的正则表达式一个new RegExp
joined
通过|
...
的new RegExp
只承认一些Object.keys
但不是全部。我需要RegEx
来动态创建它自己。
如果我把一个静态的RegExp
放在...它工作得很好。
演示不能正常工作
演示完美的作品
but I have to force the Regex to know what to look for

是否使用grep或类似的命令行上的东西的工作? –
我不熟悉'grep()' –
我只想测试'true'或'false' –
