I'm actually fighting with Promises on js. I have a function where I want to return a value.
How do I call the return value?
I searched various sources, but didn't get the hang of it.

Thankyou very much in advance!!!

class ReadFile{
    constructor(){
        this.fs = require('fs')
    }

    async readData(pathToFile){
        const readStream = this.fs.createReadStream(pathToFile, 'utf-8'); 
        readStream.on('data', (chunk) => {
            return chunk;
        })
    }
}

const read = new ReadFile();
read.readData('./resources/src/index.html').then(console.log);
