It looks like it's just assigning the scope variable m to true (also false in the m=!1 case.

It's minified code and m=!0 is fewer characters than m=true.

Well I hate that. Is there a reason m=1 wouldn't be the same thing as m=!0?

Types are dynamic so I think the ! operator converts int to bool in JS

1 is truthy, but not the exact same thing as true, and the distinction can be important.

1 != true, 1 is an int, true is a boolean
