How to get Ethereum price on the title of a Coinbase.com tab

coinbase_eth_price_tab_title.js

/*
Unable to find a chrome extension to display ethereum price
on my browser in EUROS, i decided to make a small script to
set the tab title with it every 2 seconds
 
 All you need to do to use this script is to paste it in
 your browser console.

window.setInterval(function() {
    // This class selects the prices elements. This might need to be changed.
    // In order to adjust this css class inspect the element that displays the
    // actual price. To do that in chrome just use CTRL+SHIFT+C and click
    // on the price. Extract the first css class of that div.
    var pricesElementClass = 'PriceChart__HeadingPrice-iOthZP';

    // This will create an array with all the prices
    var pricesHTMLElements = document.getElementsByClassName(pricesElementClass);

    var bitcoinPrice = pricesHTMLElements[0].innerText
    var ethereumPrice = pricesHTMLElements[1].innerText

    // set the title
    document.title = ethereumPrice;
}, 2000);
