don't set port hardcore i.e.,
port = 3000;
Instead set it like this -
port = process.env.PORT||3000; <- This is the correct way
port = 3000||process.env.PORT <- This is the wrong way as int it 3000 will get more
preference than process.env.PORT because
assignment happens from left to right
And don't have 3000 in front
