Lemon grammar file for Javascript

Hi,

Would the expert help me to point me the direction of solving the
conflicts of the javascript grammar file?
I got about 21 conflicts reported by lemon.

The grammar could be relax a bit to resolve the conflict as the input
is assumed to be all valid input.

Sorry for unable to attached the file as attachment.
