Step 1: In Chrome, go the website that you want to extract links from, like https://www.codeschool.com/.

Step 2: Open Chrome Developer Tools by pressing Cmd + Opt + i (Mac) or F12 (Windows) in the same tab.

Step 3: Click the Console panel near the top of Chrome Developer Tools.

Inside the Console panel paste the JavaScript below and press Enter:

var urls = document.getElementsByTagName('a');
for (url in urls) {
    console.log ( urls[url].href );
}

Now you will see all the links from that particular web page.
