The console can also evaluate conditions. Set a breakpoint on line 20 and reload the page. Leave
execution stopped at the breakpoint, and Step Into the
for
loop's condition.
Go to the Console, type the following, and press Enter:
timesTable <= 12
Because this is the first time the loop has been run, as shown in Figure 18-12,
timesTable
is equal
to
1
so the condition
timesTable <= 12
evaluates to
true
.

You can also use the console to access properties of the BOM and DOM. For example, if you type
location.href
into the console and press Enter, it will tell you the web page's URL.
Note
You can evaluate any JavaScript in the console, and it executes within
the scope of the page and/or breakpoint. This makes the console an extremely
powerful tool.
