Answering the Front-end developer JavaScript interview questions to the best of my ability.

Explain event delegation

Sometimes you need to delegate events to things.

Explain how this works in JavaScript

This references the object or "thing" defined elsewhere. It's like "hey, thing I defined elsewhere, I'm talkin' to you."

Explain how prototypal inheritance works.

Moving Authy to 1Password

1Password 5.3 for OSX, 5.2 for iOS, and 4.1.0.538 for Windows support OTP. I've been using Authy for a while now, but the fact is, I haven't really been using 2FA for some time.

I like the control I get with 1Password, but I didn't want to have to reset all my OTP right away, that would suck. So, I got to dissecting the Authy Chrome App to see what I could do.

Run the Authy Chrome app and make sure it's unlocked.

Now, enable Developer mode in Chrome. We'll need this to inspect the background application that stores al
