$password.focus(passwordEvent).keyup(passwordEvent).focus(confirmPasswordEvent).keyup(confirmPasswordEvent);

Hello,

I can't understand this line very well.

I understand why the () is not necessary at the end of "passwordEvent" and "confirmPasswordEvent" but I don't know how this line works.

Could you help me please?

Thank you.

I'm not sure if this is correct, but basically my understanding of what happens is this:

1) when the password field is selected, it calls the passwordEvent function to check if the password is valid (i.e. has more than 8 characters) and to hide/show the hint. 2) after each keypress, it calls the passwordEvent function to check if the password is valid and to hide/show the hint.

That's what it was doing before, but the problem was that if you wrote the password, wrote the confirmation, and then changed the password in the first field, the tips would no longer be correct.

So we add the confirmPasswordEvent function to the inputs on the password field.

3) when the password field is selected, it calls the confirmPasswordEvent function to check if the password and the password confirmation are the same 4) after each keypress, it calls the confirmPasswordEvent function to check if the password and the password confirmation are the same.

This makes it so if things match, and then a change is made so that they don't, the system provides the appropriate tip.
