clang-format complains about the missing semicolon?  AFAIK, it's valid JS code. 
Too bad clang-format doesn't just add the semicolon, if so.

According to chromium/google JS style, it is not a valid style.

When there is a missing semicolon, clang-format pulls the next line to here.
That causes the some error like "unexpected identifier...".

           source.start(0);
           context.startRendering();
         });
