forEach -> for

Hi there 👋

cycler's Issues

Not safe solution

forrer - does not preserve encapsulation, how this does forEach

For example take this code:

var forrer = require('forrer');

var code = 'function main() { var a = "Hello World"; arr.forEach(function(a) { console.log(a);  }); console.log(a);}';

console.log(forrer(code));

after transforming we get:

function main() { var a = "Hello World"; for(var _i=0,a,_m=arr;_i<_m.length;++_i){a=_m[_i]; console.log(a);  } console.log(a);}

How you can see variable a from cycle shadow a which declared inside main function.

How quick solution you can wrap cycle in self execution function:

function main() { var a = "Hello World"; (function(){for(var _i=0,a,_m=arr;_i<_m.length;++_i){a=_m[_i]; console.log(a);  }()); console.log(a);}
