This console is where you’ll see any messages you pass to console.log in your JavaScript programs. If you don’t see “Howdy partner”, go ahead and load the page (or reload it), and you should see the message appear. If you’ve already loaded howdy.html into the browser, you should see “Howdy partner” displayed in the console. It’s fine to leave it as a separate window however, if you want the console to appear in the same window as your page (as shown here), then try closing the console, making your browser window bigger, and then using the menu to open the console again. If your browser window is small when you open the console, you may see the console open into a completely separate window.

It’s also where you’ll see errors, if your program has any, so it’s a good idea to open the console when you’re working on a program so you can see any errors that pop up.

This is where you’ll see any messages you pass to console.log in your JavaScript programs. If you don’t see “Howdy partner”, just reload the page. The Console will open at the bottom of your browser window, and you should see the message “Howdy partner” displayed: To access the developer console in Chrome, first load the howdy.html file into your browser, and then use the View > Developer > JavaScript Console menu (Option-Cmd-J):

So be prepared to experiment a little if your console doesn’t look exactly like the examples below (although we’ll do our best to keep this information up to date with the most recent version of each browser). For instance, Safari version 6.1 has a very different looking console from Safari version 6.

Not only that, but the browsers change the implementation of the console occasionally.

With every browser, you’ll use a slightly different way of accessing and using the developer console.
