title: Question about Optional chaining and Nullish coalescing JavaScript operators support in PhpStorm
body: <p>I wanted to ask if anyone knows how one can support the JavaScript nullish coalescing operator (<code>??</code>) and the optional chaining operator (<code>?.</code>) in PhpStorm. </p>
  
  <p>Currently I am developing a project in react-native in PhpStorm, both operators work fine but PhpStorm sets an <code>expression expected</code> error and all files using these operators become error underlined.</p>
  
  <p>How can I add support for these features so the IDE is happy?</p>
