title: NodeJS + Javascript how to export value instead of a promise?
body: <p>I'm new to NodeJS+JavaScript. In the following JS the excelData returns a Promise when require from another JS. In the importing JS I can resolve and get it's value. But without exporting a promise, how to export the array directly? </p>
  
  <p>I need this because I have a JS where promises are not supported.</p>
