Key moments

In this episode, we’re going to take a deep dive into the Document Object Model, or DOM for short. Nicole explains what the Document Object Model is, what it looks like, and what we can do with it. And because we can’t touch on everything, more resources are included for you to go forth and dominate the DOM.

I’m so excited to share with everyone a basic introduction to JavaScript and DOM! Although I discuss the basics in this podcast episode, it is far from the amount of information and resources that exist across the web. Thus, I have included several resources to help you get started.

A note about these “techy” episodes

I just want to remind listeners really quick that my overall intention in these “Intro” episodes isn’t to go into depth, or even to “teach” people. Thus, I want to create curiosity for these types of topics and pose the questions that these topics provide answers to.

Because there are literally a million and one tutorials and templates out there for JavaScript and DOM that are fantastic, I will happily round the best that I’ve found up for you to continue on your journey of question-asking and answer-seeking in the world of web development.

What we’re doing here is creating valuable context. Context aids in learning. If you like what you hear about Document Object Model, follow the links included, and you’ll find that even if you’ve never heard about DOM before listening to this episode, your brain has now built enough of a context about it that you’ll start to ask yourself questions, and as you learn about it further, you’re not encountering these topics for the first time.

It’s kind of like skimming a book before you really read it. I’m not interested in recreating the wheel; I’m interested in helping my listeners. And the end result of listening to these Intro episodes is that you experience calmer learning with better retention and less frustration.
