Typescript, how to pass “Object is possibly null” error?

Question

I\'ve got the \"Object is possibly null\" error many times and usually I use a safety \"if statement\" in case it returns null.

I\'ve got the following function:

If you really know that in executing time you dont have a error here then just put :

 (overlayEl as any).current 

If not, better use:

    if (typeof overlayEl !== 'undefined' &&
      typeof overlayEl.current !== 'undefined' &&
      overlayEl.current === null) {          
      return;
    }

    // Or

    try {
      // you code here ...
      // This is fine way to check by order -> parent.parent.FinalInstance
      // Also try & catch will handle all bad situation about current error
      overlay &&  overlayEl.current && overlayEl.current.focus();

    } catch(e){
       console.log("Real null >> ", e);     
    }

  // Suggest if i am wrong in syntax somewhere ,this is fast answer ;)
