"Get Started" says to open the console. What's the console and how do I open it?

I’m up to the step of Get started with Apollo Client - Apollo GraphQL Docs
that says:

Run this code, open your console, and inspect the result object.

However, I don’t know what console it’s referring to or how to open it. My browser’s Javascript console when visiting http://localhost:3000/ doesn’t seem to know about any “result” object. My terminal running npm start doesn’t show any output relating to a result.

What console is the tutorial referring to here?

The (result) => console.log(result) in the code should log something onto the browser console after the query has been successfully made.

Thanks. I ended up installing the Chrome Apollo plugin and that’s been working great. Still, this would be a good thing to clarify in the tutorial.
