Can't return value from RTF parser

[8483]

Maybe I need a break from coding, but I really don't get why I can't retrieve the value from the function...

Can anyone please tell me what I'm doing wrong?

const parseRTF = require("rtf-parser");

let string = `{\\rtf1\\ansi\\deff0\\nouicompat{\\ etc...}`;

function convertRTFtoPlainText(string) {
    parseRTF.string(string, (err, doc) => {
        let result = "";

        doc.content.forEach((item) => {
            if (item.content) {
                item.content.forEach((span) => {
                    result += span.value;
                });
            }
        });

        console.log(result);           // <-------- Shows the converted string

        return result.trim();
    });
}

let value = convertRTFtoPlainText(string);   

console.log(value);                    // <-------- undefined

You should use Promise here

const parseRTF = require("rtf-parser");

function convertRTFtoPlainText(str) {
  return new Promise(
    function(resolve, reject) {
      parseRTF.string(
        str,
        function (error, doc) {
          if (error) {
            return reject(error);
          }

          let result = "";

          doc.content.forEach((item) => {
            if (item.content) {
              item.content.forEach((span) => {
                result += span.value;
              });
            }
          });

          resolve(result.trim());
        }
      );
    }
  );
}

const string = `{\\rtf1\\ansi\\deff0\\nouicompat{\\ etc...}`;

convertRTFtoPlainText(string).then(
  function (value) {
    console.log('convertRTFtoPlainText = ' + value);
  }
).catch(
  function (error) {
    console.error('Error in convertRTFtoPlainText', error)
  }
);
