Utilizing a simple web page test with Selenium Webdriver JS?

Minimal experience with automated testing. Gone through a fair amount of Selenium crash courses, but I seem to not understand how to utilize Selenium properly to begin with.

I'm sure there's much wrong with my code but here's what I've got so far: Using Chromedriver Javascript Don't understand the basic difference between the use of promises v. callbacks

Feedback I've received: My code is automating a lot of clicks but not testing to see if anything's actually passing or failing - just clicking stuff doesn't tell me anything if I'm not checking the result.

/*

var webdriver = require('selenium-webdriver');
var browser = new webdriver.Builder().usingServer().withCapabilities({'browserName': 'chrome' }).build();

    link.click();
