(Nodejs) Converting form Raw Binary Data to usable Base64 - (Page response)With Puppeteer !

Hello. Can anyone please convert the variable 'result' in the code below, to base64 format? When it's converted it should be shown as jpg image output in [login to view URL] Notes : 1) 3rd party pakage 'puppeteer' will be needed. I will be deeply appreciated! Thanks :) // /* 20190208 Newly Acquitred Standard... const puppeteer = require('puppeteer'); (async () => { const browser = await [login to view URL](); const page = await [login to view URL](); [login to view URL]('response', response => { [login to view URL]().then( function(result) { [login to view URL](result); }); }); await [login to view URL]('[login to view URL]'); })(); // */
