@ApoorvSaxena, from what i can see there is not a merge conflict perse. the src file has to be updated and then the dist shall update to right? The changes are made in a dist file which is wrong right?

https://github.com/ApoorvSaxena/lozad.js/blob/4509b99e2631665224383247801ec42303698695/src/lozad.js#L13 it should be change here, but than again, the dist is a production folder and should be reuploaded when creating a build in order to get rid of the conflicts.
