We've gone through a few games recently in the earlier sections, and this one is going to be going
into, again, more of a utility type function with JavaScript, where we've got an input, feel that
we want to count how many characters are still available within the input field and how many characters
are added in there.
And then if there's a limit, if we only want 10 characters, then we're going to output a message whenever
we detect that the character count is above what is allocated for the input field.
So this is a relatively simple application.
And the objective here is to get more familiar with string that variables and string methods, as well
as using input fields and text areas and dynamically updating and changing messaging for those inputs.
So let's try this out.
So I've got my input field and I can type in and I can see how many characters I have left.
I can also see that once I try to go over the allocated amount of characters, JavaScript is going to
prevent that from entering into the field.
