No , there is no error message, it's juts not working .
Let me explain you in little more. when i'm working with gulp everything is working great.
but when use gulp --production it's shows this in console.
and after that it's minified my all files but when i use that file nothing is happening. i'm logging something to the console but i can't see them.
little strange but it's true.
Oh shitt, i got it why it's happening . actually i'm trying to log some messages into browser console so normally it's working fine but when i run gulp --production it's actually automatically stripped out all the console.log from my javascript. that's why i can't see that in console after building production. howvere an alert will do the trick because at production alert will not strip out automatically .
actually i didn't knew it before , yesterday i learned about webpack so not i recall that. :)
