I make websites. Sometimes I make music. Over the years, I’ve noticed an interesting pattern of behavior from some musicians—often self-taught—who think of themselves as creative types: they display an aversion to learning any music theory. The logic, they say, is that knowing the theory behind music will somehow constrain their creative abilities. I’ve never understood that logic (and I secretly believe that it’s a retroactive excuse for a lack of discipline). To my mind, I just don’t see how any kind of knowledge or enlightenment could be a bad thing.
Alas, I have seen the same kind of logic at work in the world of web design. There are designers who not only don’t know how to write markup and CSS, they actively refuse to learn. Again, they cite the fear of somehow being constrained by this knowledge (and again, I believe that’s a self-justifying excuse).
Nonetheless, I think that many front-end devs have a feeling that they should know what’s going on under the hood. That’s the natural reaction of a good geek when presented with a system they’re expected to work with. Now, thanks to DOM Enlightenment, they can scratch that natural itch.
You might not end up using this knowledge in every project. You might decide to use a library like jQuery instead. But now it will be your decision. Instead of having to use a library because that’s all that you know, you can choose if and when to use a library. That’s a very empowering feeling. That’s what knowledge provides. That is true enlightenment.
