We talked a bit about what the console panel is—essentially, a JavaScript command line. We can execute any JavaScript code we want, and interact with any page element. There are two primary components to the Console panel—the console log area and the input area.

The console log area will display information about any errors, along with displaying any code that is entered. The input area allows us to either enter a single line of code or, by clicking on the red arrow on the right side of the input box, multiple lines of code.
