Well, if you insist, you can

var $break = 1;

which is the same as C# in terms of characters ;)

Seriously, you cannot use reserved keywords as variables, but they are allowed as property names:

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

Also, do note that the repertoire of the reserved words varies depending on the strictness. For example,

var interface = 1;

is valid in the non-strict mode, but breaks once you add use strict to your script.

You can't use Javascript keywords as a variable name.
