Javascript condition & 0 value

Recently, I had to debug an error caused by a Javascript condition:

  if (utcOffset) {
    // do fancy things
  }

The problem with utcOffset param is that i can be a 0 value.

Unfortunatley, there is no better way to solve this than using the following condition:

  if (utcOffset !== undefined && utcOffset !== null) {
    // do fancy things
  }

This way a 0 value will be passing the condition.
