Tesseract.js hangs in console

Question

Problem: I have a very simple script using tesseract.js locally (which getting to work was a pain of its own), and when i run the function, it logs my text and hangs without ever moving onto anything after the tesseract function.

var Tesseract   = require('tesseract.js');
Tesseract.workerOptions.langPath = './eng.traineddata';

function parseImg(img){
  Tesseract.recognize(img)
.then(result => console.log(result.text))
};

parseImg('./undefined.jpeg')

The function does work, and it does log the text from my image, but i cant figure out how to break from the function. Any guidance would be greatly appreciated!

var Tesseract   = require('tesseract.js');
Tesseract.workerOptions.langPath = './eng.traineddata';

function parseImg(img){
  Tesseract.recognize(img)
    .then(result =>{
        console.log(result.text)
        //This guy right here
        process.exit()
    })
};

parseImg('./undefined.jpeg')

now.

import Tesseract from 'tesseract'
Tesseract.workerOptions.langPath = './eng.traineddata';

async function parseImg(){
    const result = await Tesseract.recognize(img);
    console.log(result)
    return result
}parseImg().catch(e){console.error(e.stack)}
