title: watchPosition() and getCurrentPosition
body: <p>What is the difference between <code>getCurrentPosition()</code> and <code>watchPosition()</code>. I read several articles about <code>getCurrentPosition()</code> and <code>watchPosition()</code>. But none of was clear to me. As far as I'm understand <code>getCurrentPosition()</code> update location only one time But <code>watchPosition()</code> continuously update location. I'm I right?? </p>
