In C# we have the option to use it using @, is similar option available in JS 在C＃中，我们可以选择使用@来使用它，这与JS中可用的类似选项

Answer 1

Well, if you insist, you can 好吧，如果你坚持，你可以

var $break = 1;

which is the same as C# in terms of characters ;) 就字符而言，这与C＃相同；）

Seriously, you cannot use reserved keywords as variables, but they are allowed as property names: 认真地说，您不能将保留关键字用作变量，但可以将它们用作属性名称：

myObj = {}
myObj.break = 'whatever';

Also, do note that the repertoire of the reserved words varies depending on the strictness. 另外，请注意，保留字的库根据严格性而有所不同。 For example, 例如，

var interface = 1;

is valid in the non-strict mode, but breaks once you add use strict to your script. 在非严格模式下有效，但是一旦在脚本中添加use strict就会中断。
