Looking at the JavaScript Promise Collection Methods / / No Comments Let me begin by saying that "Promise Collection Methods" is not something I’ve seen mentioned elsewhere, but is my own way of referring to the various methods of the Promise API that work with multiple promises.

Detect Caps Lock with JavaScript / / No Comments Anyone is capable of having their caps lock key on at any given time without realizing so. Users can easily spot unwanted caps lock when typing in most inputs, but when using a password input, the problem isn’t so obvious. That leads to the user’s password being incorrect, which is an annoyance. Ideally developers could let the user know their caps lock key is activated. To detect if a user has their keyboard’s caps lock turn on, we’ll employ KeyboardEvent‘s getModifierState method: document.querySelector('input[type=password]').addEventListener('keyup', function (keyboardEvent) { const capsLockOn = keyboardEvent.getModifierState('CapsLock'); if (capsLockOn)... more → Posted in: JavaScript Tagged with: Caps, Detect, JavaScript, Lock

Using Generative AI as Your Content Assistant / / No Comments Last week I had the honor of presenting one at TheJam.dev. This was my first presentation on generative AI and I got to share what I thought was an interesting use case – helping with the writing process. Now to be clear, I don’t mean using GenAI to write blog posts, that would be a horrible idea. (IMO!) Instead, I looked at how it could help with some of the process. Let me back up a bit and give some background. I’ve been a fan of John Birmingham for many years now. He’s an author who writes in the military/sci-fi/etc genre and has some pretty fascinating ideas. I initially discovered him via his "Axis of Time" trilogy which dealt with the idea of a modern... more → Posted in: JavaScript Tagged with: Assistant, Content, Generative, using
