"++" changes the behavior code

[mlabanowicz]

Example:

origin:
var i = 0;while (i < 10){console.log(i++);}
OUTPUT:
0,1,2,3,4,5,6,7,8,9

after fixmyjs:
var i = 0;while (i < 10){console.log(i += 1);}
OUTPUT:
1,2,3,4,5,6,7,8,9,10

Yeah it does, it's one of those "use catiously" rules.

I usually like to run the rules by themselves and git diff after each fix run. Nowadays I'm using eslint --fix though, it's still a good workflow for any auto-fix tooling like codemods.
