How can I access the value of function result into a variable, actually I am trying to get the value from this function and save it into a variable so then I can submit this value into POST request, but right now I am unable to get the value, what I did in this function I have puppeteer node js code I have a result of OCR into a variable and I just need to submit this OCR result into POST login function.

  let res = "";
  // Run and wait the result
  ocrSpaceApi.parseImageFromLocalFile(imageFilePath, options)
    .then(function (parsedResult) {
      //console.log('parsedText: \n', parsedResult.parsedText);
      res =  parsedResult.parsedText;
      console.log(res);
    }).catch(function (err) {
      console.log('ERROR:', err);
    });
    console.log(res);

want the parsed result in RES varaiable.
