Javascript for...of loop compiling issue

[SongX-23]

• Recently, I spot a javascript compile issue from Web Essentials on Visual Studio 2015.
  The following is my plain javascript code.
  

• After it has been compiled and published to the server, the compiled javascript code is not right and it throws an error because it tries to loop through itself.
  

• If I change the way of writing iterations to old fashion, the compile issue is gone.
  

• Many for..of loops have this issue in the same file. Probably worth to have a look. :)

• I cannot really give you a self-contained example. Sorry about that
