What does : and ? means in JavaScript and React [duplicate]

Question

It's quite hard to find this answers on Google because this characters are used for other purposes.

This is a example in React:

return (
   <div>
   {sec == 0 ? ( // This one
      ""
   ) : ( // And this one
      <div></div>
   )}
   </div>
)

Thanks
